[MC-126892] Everything broke (Ticks, redstone, maybe more)

So i have this singleplayer world where everything broke when i opened it in the latest snapshot 18w10b. So what broke? Hoppers, droppers, redstone, fences i couldnt even pick up items and the beacon effects wouldn't update to 0:16 sec. So I went back into the snapshot archives and I found out this was still the case in snapshot 17w47b. I read the snapshot page: https://minecraft.net/nl-nl/article/minecraft-snapshot-17w47a
and found out that everything broke in this snap. But I guess the issues are still not resolved as of like 4 months later in 18w10b?
tldr Very slowtickrate(i guess) and redstone stuff not working (updates in game neither such as beacon effects updates) been happening since 17w47b still happening in 18w10b.

Please do not mark unreleased versions as affected.
You don't have access to them yet.

Cannot reproduce, please attach the affected world, if possible, if not, upload it to another site (eg mediafire, dropbox, etc.) and provide the link.

While it's uploading. I want to say the following: Look at the behaviour of redstone (you can find redstone almost everywhere), drop something on the ground and try to pick it up or even try eating the meat. I have tried creating a new creative world with this snapshot and indeed the redstone works perfectly. This world is very old, but it still works in 1.12.2. I have made a zipfile of the worldmap (the world is around 600 mb). I hope you have the same problems as i encounter:

Edit: I said it still works in 1.12.2: I am referring to the fact that everything is working as intended (so i dont have the problems i mentioned).

You have a lot of entities in your area. After killing them, the tick rate improved significantly, beacons update as intended, items can be picked up, eating doesn't take forever, and most redstone components seem to work.

I will try that this afternoon, but it's still a problem that my world can run in 1.12.2 (with these entities) but not in snapshot 18w10c (with these entities). To be fair that's considered a huge bug to me, which means (not to be rude) that it's still not resolved.

Okay so what I now did was, kill most of the cows,chicken and sheep and next to that kill the 130 boats which are actually floating around when you load the world (this was an elytra launcher, but it breaks when you load it up) So i've done all that. Most of the time the ticks are fine, but things are stil weird, like redstone dust which isn't connected or fences who aren't connected...... UNTIL...
(first background story)
I have this iron titan (big iron farm, with 32 villages on 32 x something blocks) at my world spawn, but when I go there (either throught the nether portals OR through the /tp command) my game crashes. The one time it didn't break is when i saw in NBT explorer that there weren't anymore villages on that iron titan(32 went down to 0). The time the game didn't break i looked throught the redstone and i noticed a piston and redstone block missing, which controlled the timing of an item through the netherportal (the continuation of throwing items throught a netherportal actually keeps the chuncks loaded (i think)) But because the redstone contraption behind that throwing-in-an-item broke actually implicated that the chuncks wouldn't load, so it broke and the chuncks became corrupted. I'm just asuming this.
TLDR: Killed many annoying entities, things that should be connected aren't (fences and redstone) and a timed-item-throw in a nether portal AT spawn crashed my game, because a pisten/redstoneblock aren't loaded properly. TLDRDR this aren't loaded properly.

Maybe I should make a new thread, because my world just crashes now when i load it up. I killed all the boats and I'm away from my main base(with a ton of entities, but still playable in 1.12.2). I'm now at the Iron Titan(the iron farm with 32 villages). And when i load it in 1.12.2 it works fine, but when i load it in 18w10d it just crashes.... So it's a different problem (I don't have many entities at spawn where the titan is)

Hi, thanks for your report. I looked over what you described, but given the size of your world I'm not sure where to look for the specific things you describe. Additionally, I think there may be several bugs happening to you simultaneously. I'm going to resolve this report, can you please create one new ticket for each of the following issues:

Redstone dust and fences which aren't connected
Piston and redstone block disappearing from your iron farm wiring
The game crashing when you visit the area of your iron farm
Your world just crashes when you start the game

Where relevant, please include a crash report or launcher log. Also, please include the download link to your world in all these tickets, and, if relevant, give coordinates for where the issue can be observed.

edit: just noticed this report is already resolved. Please create the 4 new tickets anyway, they sound like valid issues.

jurriaan engels 2018-03-10T23:20:04Z

The crashes are the same. See this thread: https://bugs.mojang.com/browse/MC-124123 For the redstone, fences not connecting see: https://bugs.mojang.com/browse/MC-127136.

I can't reproduce the piston and redstone block disappearing as air block, because when i go to the iron farm(spawn chunks) the world crashes, and keeps on crashing when i reopen the world.

[Mod] redstonehelper 2018-03-10T23:53:01Z

Thanks for following up. When you open the world in 18w08b, can you reproduce the disappearing blocks?

jurriaan engels 2018-03-11T11:01:50Z

Hey yeah i opened it up and went throught the netherportal and my world still crashes.

. So I can't look if the blocks disappeared.

[Mod] redstonehelper 2018-03-11T17:58:53Z

Right. Once MC-124123 is fixed, please do check again.
