I can confirm this is still an issue as is BDS-19101

We are running a BDS server with 6 cores and it's maxing out or CPU on multiple cores when people go into the Nether.

My game did that for a while after the .200 update but it finally went away. 

We're experiencing the same issue on a BDS. Sometimes chests have items in them, sometimes they're empty, but every time they crash the server if someone opens one. I have to go into creative mode to delete the chest. Thankfully any contents inside are not lost during the process. We crashed twice in a row yesterday. Please fix asap. 

The MCPE text that has a line through it is that way because those issues are duplicates of other issues or resolved. 

It looks like your world may be corrupt. Do you have a backup of it before the update? Can you revert to the previous version and see if it still works?

I run a BDS server. Prior to the 1.16.100 update, it took about 6-8 people on at one time to lag out our world, and that was with a lot of redstone builds in it. Prior to the update our server would run around 30% of CPU power with one player on and increase as the number of players joining increased, but rarely went over 100% unless there were 6-8 players on. 

We started a new world when the update came out and now the server CPU pegs out at 100% with one player on and the block lag is nearly unbearable. There's a ton of other general lag issues as well, IE. smelting takes forever even in blast furnaces and smokers, grass takes forever to grow, sheep take forever to get their wool back, fishing is noticeably laggy when reeling in a catch, etc. 

I've been monitoring the CPU's activity during certain instances and I've noticed a couple of things since the update: 

1. Going through a portal will force the CPU to use 1000% plus of it's power. 
2.Flying with Elytra causes undulating "waves" of lag spikes well over 200% of CPU power. 
3. With zero players on the server runs at 2-3% CPU.
4. Running through the Nether causes undulating spikes in the CPU.
5. Sometimes mining with UB3 pickaxe causes undulating spikes in the CPU. 

We are on a server set up by a small provider. We do not share the hardware with others. Our hardware specs:

Intel Core i9 9900K up to 5.0 Ghz
Unlimited NVMe SSD
DDR4 ECC Ram 2133/2400mhz

I think there needs to be  more information. Is vanilla resource pack missing from the world? Have you reviewed your server properties to make sure everything is loaded and set correctly?

I think you've posted this issue in the wrong section. It should go under the Bedrock Code Base project to the Bedrock Dedicated Server Project. You're talking about a single world, this is the place for people who have or run servers. 

PS Sorry you lost your build. 

I'm experiencing the same thing as Alex Mercer above. 

Villagers disappear after going to bed. If I log out and log back in, they reappear or if I walk away some distance and come back they reappear. I've also see this happen with an entire village. I came across the village that looked active but there were no villagers in it. This was before I realized they were disappearing. Another player went to the same village later and all the villagers were there. 

Is this the same issue or do we need to open a new ticket? 

I can confirm this is happening on my server as well. We started a fresh world with the update. No redstone builds yet, but the lag spikes are terrible! Prior to the update, our old world didn't significantly lag unless we had 8+ players on at once and we had a lot of redstone contraptions. 

This is our current server hardware:

Intel Core i9 9900K up to 5.0 Ghz
Unlimited NVMe SSD
DDR4 ECC Ram 2133/2400mhz

Since the update, when only 2-3 players are on, the lag is horrible and the lag spikes seem to be constant and random. 

As a side note, I did experience tons of lag in a single player world while looking for the new seed for our current world. I was the only one on and in creative mode. 

 I also want to report that the lag is causing mobs not to spawn, passive or aggressive. We play on hard mode but it's more like peaceful. The only mobs that spawn normally, that I've noticed are drowns. Very few mobs are spawning in the Nether. 

I haven't noticed players being kicked when this happens but wonder if this isn't part of the terrible lag we've been having since the update? We started a brand new world after the update came out....its a week old and nearly unplayable due to lag. 

Same. Windows PC on a BDS Server

Affects 1.16.100 on Windows PC. My off hand disappears when holding a map as well. 

I can confirm this is now happening on PC and on BDS servers. Even if you're not in direct line of site to the person opening the shulker it causes the game to freeze and must be restarted. 

Along the same lines as the game freezing issue: 

I witnessed a player standing on a shulker, then when another player opened the shulker the player standing on the shulker appeared to teleport across the room as the shulker opened and then teleported back as the shulker closed. The player on the shulker did not experience the teleportation. 

I'm not sure if this is related and if not, I'm glad to open a new ticket, but we've been having issues with parrots disappearing on our server as well as traded and locked villagers loosing their trades and attaching to random work stations. 

With the parrot issue, I and other players travel through their portals into the nether while their parrots are sitting in their bases. The parrot or parrots (sometimes multiple) then appear on the players shoulder after they've crossed into the Nether. When this happened to me, I was unable to remove the parrot at my portal in order to send it back through so I sat it down and went into our spawn portal. When I came back my parrot was gone, and oddly, so was my parrot that was still at my base. (My base mate's parrots were still there but were no longer sitting and were flying around.) The same issue happens with other players although in some instances, when those players have found their parrots in the Nether, they have taken them off their shoulder and let them fly through the portal while they walk through, at which time the parrots disappear. Often those parrots reappear minutes, hours or days later at the players base. (My parrots have never reappeared. It's been over a week)

Regarding the villager issue: My base mate accidently brought the bad omen to our base. After defeating the raid I went to trade with my villagers and noticed my Unbreaking III villager was now a fishermen. I thought maybe it had died during the raid and the village had spawned a fresh villager who just grew up fast...lol I reset him back to an Unbreaking III and traded with him. A few days later I went back to trade again and he was once again a fishermen. Furthermore, another villager had also lost it's trades and was also a fishermen. 

I'm not sure if this is the same issue because I'm on the 1.16.1 update but I stood for a full night cycle at the top of a  building in a plains area and not a single, solitary hostile mob spawned and we're on hard level. Tried again today and stood on top of a tree. Nothing. Hostile mobs are spawning like crazy in the new nether, but nothing in the overworld.

This is the only report I've found on this issue and it's not for the released version so I'm gonna make a new bug report. 

I've had several players complain about the same issue. They are right clicking correctly and the glowstone light decreases as expected but when they die they're respawing in the overworld. I have 138 levels, but I'll sacrifice myself today to verify and report back. 🙂

I haven't noticed the proximity damage issue, I'll watch for that today, but I can attest the amount of damage done is excessive. I thought it was because they buffed them and we're in hard mode but if you're having the same issues in easy maybe it is a bug.

Can confirm buttons work in place of pressure plates when placed where the pressure plate would normally go.

This is not a bug in Bedrock, it's part of their loot table and an advertised barter drop.

Magma Cube's are also spawning on half slabs placed on the bottom.
