[1.7.0B2] Repeated errors in The Maze Alternate

[gykdu1]

While in The Maze alternate (the one with the holes in the floor), a repeated error occurred when opening a backpack style chest; the first time it happened on the first floor, it only happened once on the first action on opening the chest, the second time on the second floor, it occurred every action after opening the chest. Error reports are attached. Error is the same in the log files (has the same error and stack trace) and is as follows:
