How to Reproduce:

  • Create a new world (creative with seed 18w48a, any seed will work)

  • Join the world and execute 

    /locate New_Village
  • This will yield a village of the new type somewhere around x700, z-1470. Teleport to this village using the provided command.

  • And the game will crash.

Edit:

It appears to just exploring the world a bit too fast also causes the crash to happen. Did happen as often as using the command. Upon reopening the world the game will crash with a tick loop.

I can confirm this issue as well for Minecraft 18w48a. If I try to teleport to the location of the New_Village the game crashes. Also when I try to reload that world the game crashes again.

I have this issue too.

Could be that MC-140239 and MC140232 are related if not the same. See my comments for those issues.

It happens to all newly added structures

pretty much the same thing i reported on MC-140281 

I also can confirm this as true. It's rather annoying I mus say.

OK, this issue has a seriously misleading name. My issue was resolved and I was confused because of the name. Anyway, DON'T TRY TO RE-OPEN THE CRASHED WORLD. I did this and it crashed again. However, it gave me details, listed below:

The game crashed whilst ticking memory connection

Error: java.lang.AbstractMethodError: bxx$$Lambda$1057/1198265211.a(Lcom/mojang/datafixers/Dynamic;)Ljava/lang/Object;

I obviously cannot interpret what this means, but please include the fact that I found this when and how I did. Oh, and please change the name to something probably along the lines of 'Generating Chunks Too Quickly, Especially Teleporting to New Villages, Results in an Unopenable World And Crashing.
