/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
MC-126244 '/locate', explorer maps, and treasure maps can cause extreme TPS lag, even leading to a complete server freeze if structure generation is turned off
