I’ve had this same bug (on Official PvE server 1500); it seems to be caused by the same thing that is causing all of the “inventory bugs” (the item sorting feature/ function); it seems to take up all of the server’s/ game’s runtime resources and leads to dropped calls… eventually cascading into “all kinds of other problems” (like not correctly loading mesh coliders and thus causing the “falling through foundations bug”) and ultimatly crashing the server/ game.
