[MC-129754] Putting down lava freezes everything and then crashes the game when quitting

When you put down lava, every mob freezes. You can still walk around and place blocks. The lava doesn't move either.

If you try to leave the game by saving & quitting or simply closing the game, it crashes.

It didn't make a log automatically so I had to make it manually. I uploaded it as an attachment.

I don't think it contains anything about the crash or the freeze though.

That launcher log is quite empty, please attach a crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt)

I already said, it didn't make one, so I used the launcher log.

You probably can reproduce the bug easily, by spawning slimes for example, and putting lava down. All the mobs will freeze in place.

Then trying to save & quit or exit the game will crash it.

Cannot reproduce at all, see screenshot.

This is really weird, I can only reproduce it only one of my superflat worlds.

I have 2 stacks of exp bottles, 2 enchanted turtle shells, a stack of lapis, an enchantment table and 3 slimeballs.

/gamerule doMobSpawning is false, and there's some small slimes and sheep around.

When I change to creative mode and put down the lava the small slimes freeze midair

I put the bugged world as an attachment for testing.

The world is made in 18w08b though, even though it's still bugged in 18w0c. Maybe the bug can't happen in worlds created in 18w0c+

Is this still an issue in 1.13 pre-1?

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report (minecraft/crash-reports/crash-<DATE>-client.txt) here.

Well, nothing buggy happened when I tested in 18w30a. I think this can be closed.
