Something is broken in this Santo Dominion map:
Guild of Drunken Barbarian, Storage Room (/santo_dominion/guilds/drunken_barbarian/storage_room) in Santo Dominion
Upon entering the building, one sees a big black square surrounded by grass. Walking in the square leaves artifacts of the player. There is a guard in the black square and various blades traps are visible (weird in an of itself).
This is probably an artifact of the "new guilds" update. It will take manual intervention to move the items from the old guild to the new one.
