When calling C_Container.GetContainerNumFreeSlots on Classic Era, with a bag id of -1 (the main bank bag) while the bank is open, the number of free slots is always N+4, let N be the number of actual free slots.
As far as I can tell, it looks like the extra 4 slots being reported are due to retail bank bags being 28, and classic being 24. It seems this function is using 28 slots for it's max on Classic. The same issue happens with GetContainerFreeSlots -- it returns 4 slots that do not exist on Classic for bag -1.
