Having this issue with CP booths aswell. It seems as though the bug is to do with the item points max values being switched at some point.
indoor/max = 5/0
display area/max = 0/0
additional area/max = 0/30
To place an item it is trying to add +1 to the indoor/max or display area count. But those are max set to 0.
SO it won't allow us to place item. (since we can't place item in additional area, since that doesn't exist)
The item max count for additional area should be moved to the indoor/max maximum value. This would solve the bug.
Looks like a very simple fix! Come on MA and support.
