There is a bug in the shop that gives out too much money. I already banned one user (Toohee) for exploiting this. Depending on the severity of other exploits, this will not be the only ban. I will go through the shop figures and try to find out what happened when.
In the meantime the shop will stay closed.
[Update] Found the issue. There was a bug when someone made a request for a 0 amount of items. You would not be charged then, but cancelling the item would refund the request. So the item is fixed. Also I found that toohee was the only user abusing the exploit. [/Update]
