When executing the command 'locate atum:tomb' the game just stands still. After a while the message that the structure wasn't found appears but the game is still in freeze. The player can move but all other mobs don't.
Don't know if this is really called a serverside freeze or what the right term might be but there is definitely something wrong.

Edit: Leaving the world afterwards is also not possible and you have to close the whole game.

Playing on verison 2.2.2 with curios 4.0.5.0 and nothing else.
