No, its just that the game don’t save the mobs, for example, i traped a pig far 100 blocks away from home, but I don’t have carrot, so if i have to leave to get carrot, they will despawn “immediately” After it has gone out of reach for about 50 block, but i also has no way to interact with the pig, hitting doesn’t work, so i am forced to leave and find another pig to breed...
Minecraft has a new mechanic so old ironfarms wont work, villagers no longer rely on doors, but rather beds, so try to follow tutorials for the recent version
sorry for my mistake, i didn't see the post when searching for it
