While dealing with container and inventory items, many developers use a bag/slot couple and set bag to -1 for the case of an inventory item. But a problem occurs when the bank is opened (after BANKFRAME_OPENED event being fired) because the 28 slots of the bank count as actual container slots with -1 as bagID.
