I did a chunkreset f command while 2 players were looking in loot containers in the poi. they were unable to look in loot containers anytime after that until I quit to windows and restarted the game.
Yeah the fix is to reboot the server or your pc if it's the host. I can't tell you the exact reason but I assume it has to do with changing the map abruptly and something doesn't get saved correctly but that's just a guess.
what it probably is is that the status, and therefore its contents, of a container are reset to untouched while they are being viewed. The game client kicks the player out of the view contents dialog, but does not reset a flag that says they can open and look in/loot containers.
As I said, resetting the server resolves the issue, but it is still a bug
