/locate (village/whatever is in this dimension) on a world with "no structures" when generated lags the game out. It also slows down the saving and then softlocks(I think). You cant delete it by ingame means anymore. Basicacally corrupts worlds.

To reacreat, create a world with the "no structures" option then ingame type /locate village.

Place down a tnt (or a redstone lamp), place a lever ontop of it, activate the lver

the lever wont work

Now break the tnt, the lever will not pop off.

save and exit, this will take a while

When deleting by ingame means, my game "didn't respond" and i had to force-exit it, this resulted in not having a crashlog
