Excellent!! Agreed! Hopefully before this weekend
I just thought of a way (like Spirit was saying) to get around this issue (kind of) When you start a purchase store, make sure that you only have stacks of 50 (or max stack) therefore when someone sells you the items, the first transaction will work. Now if someone sells to you in less than full stacks the next time someone tries to sell, they won't be able to as it will try to stack them in the newly formed stack. Temporary solution to a temporary problem.
