Cannot undo item if a Biscuit is received after purchase. (Item Delivery Input)

If you purchase an item from the shop, and then receive a Biscuit from Total Biscuit mastery after, you cannot undo your purchase.

I bet this would also occur when receiving Slightly Magical Boots while on the fountain as well, and will most likely be a tricky bug to fix.

I believe that these items are still counted as "Transactions", which is why you cannot re-make if a player has the biscuit mastery. The biscuit "Transaction" occurs, and because purchasing an item counts as not being AFK, this is why a re-make vote cannot be made.

Perhaps classifying a second method of item delivery would help remedy the problem? Label store-purchases as "Transactions" and flag those actions as non-AFK, while adding "Delivery" and allow that action to happen whether AFK or not? This could also solve the issue with not being able to undo purchases, if "Transactions" could be undone, but "Delivery" could not.

Alternatively, to solve the inability to re-make problem, you could just disable item shop until player presses/clicks a button, and then having time-based deliveries occur while not-afk. So if you load back in at 13 minutes, you'd receive all 4 of your biscuits and/or your boots, but be marked as AFK and not receive those items until then. BUT, this method would not solve the UNDO bug.

Just some thoughts.
