I'm having the same problem. I can go backwards without it crashing, but if I try to go forward to a new area, it crashes. 

We’re only able to play 350 blocks + away from our town still, if we visit town everything lags. Our villagers and all our animals vanished, still can’t open chests, and we get stuck there. Only way to escape is save and quit at the edge of town then reenter. We’ve tested with just one of us in the game or two, either way we get stuck. With just one of us in the game, it takes a bit longer to get to the point where you’re completely stuck, but it still happens. 

Is anyone fixing this issue? Is it still being looked at? There’s only so much we can do at the stronghold, we want to continue building our town…

@GoldenHelmet I’m not sure how to get it to do that as it’s on xBox One and we don’t have it on PC, we also don’t have Realms. Our save file is 976MB so that’s probably why we’re having so many issues. We found this morning it now works if we leave our town and go 100 blocks away, but sometimes it doesn’t generate and we run into a blue wall. We just about managed to get to the END which finally works, but we can’t go in our town at all. Chests won’t open in town and doors don’t, we can’t farm… we’re currently taking shelter in the stronghold.

New bug! Most likely related to this lag issue! If we get 100 blocks away, there is nothing. We freeze then it crashes. This update has gone well…

@GoldenHelmet No matter what, there is lag.

In our multiplayer world, we found it occurs if you’re playing alone or if both of us are there. With both of us it’s so much worse. We can’t play anymore, it’s impossible. The lag is just too much. Shame, we were just about to explore the END for the first time…

Im having the same issue when trying to put in a specific seed on my galaxy s9.

No, I haven't. I've been checking the app store all day for the update, I guess its not available for my device yet? I know update day is usually Thursdays.

This is not resolved.

Same thing on Nintendo switch 

Hello, Agreed this is not resolved! Also, please note: 

Edit: My husband said it happens regardless of if his weapon is shown on the UI or not. But it's happening exactly as the guy above says and the only fix is going in and out of the menu once or twice. So annoying!

I think it's because I'm not using the weapon. I don't like to look at the weapon and shield, so I turn them off. Since I can't see the huge object on the screen.. I can't see when it selects another item. It seems arbitrary, but really maybe it's just because I'm actually selecting it with the hidden outline of the Pickaxe? Just a thought. Either way.. this is happening to both my husband and I constantly and it's driving us mad.

@violine1101

possibly, however I am not sure.

We are having the same problem since the update.

I have tried to reboot the iPad and I've tried to uninstall and reinstall the app (I hope the worlds and purchases are saved).  It will not open even with the fresh install.  

I was able to resolve this by going into the Nether and copying the world there. After that I was able to play in my original world and copy it as normal when I wanted.

(I noticed that the amount of space it took up kept changing slightly whenever I would restart the game trying to make this work. Sometimes it would say it took up more  space, and sometimes less. I guessed maybe there was a problem loading the environment or something- maybe it happened when I’d gone into the Nether earlier today? - and thought maybe loading a different environment in-game might help it start loading things properly again. I have no idea if that’s actually what happened, but it seemed to work.)  

Oh I didn't know that. Thanks Kevin!

I can also confirm, in 1.13.2, with 6 server members and usually 2-3 online at a time, we are unable to use elytra, boats, or large numbers of shulker boxes without experiencing severe TPS lag. To the point that we get dropped out of the sky if we try flying around. Memory usage during these episodes is usually around 20% of the available 2GB.

The 1.13.2 update has drastically improved mob spawn rates in my experience (the witch farm I had mentioned in a previous comment is suddenly extremely productive). In my opinion, this issue is resolved. I hope everyone else is experiencing similar success.

I am having this problem in 1.13 Java Realms. I'm getting very sparse spawns (less than 10 in an 8 hour period) in a witch hut that I built, with the area around it made spawn-proof and my idling platform about 95 blocks above it to avoid the possible interference of underground caves.

I read the description of MC-134506 as Thilo commented above, and if this was an intentional change meant to break AFK farming, Mojang needs to come out and say that, so players know whether it's a genuine bug or expected behavior.

Using Java version 1.13, I am having what I believe is the same issue at a witch hut. There was a single witch when I found the hut; after killing it, I haven't seen any more. I spent a few hours fishing on a platform about 30 blocks above the hut roof, and there are drops in the collection chest from probably 4-6 witches. There was a series of caves under it, which I cleared of mobs and lit fully before finishing the witch farm. Likewise, the area around the farm is mostly water, with the solid blocks lit to prevent other mobs spawning.

If you want to keep the bed item, pushing the “existing” side of it with a piston as Mega_Spud suggested did work for me (Windows 10 edition) and dropped the bed.
