Describe the issue
Backpack slot breaks when Backpacked by MrCrayfish and FancyMenu are installed together. When in survival mode, the texture give the usual black and purple broken texture when the slot is empty. But when the slot is filled is looks just fine. When in creative mode though, that's where things get weird. The slot doesn't work and instead is move to the hotbar... sometimes... But then when the slot is either on the hotbar when it's there or when it's where it's supposed to be, the broken texture will always remain no matter if fill or not. Then when swapping back to survival mode from creative mode via commands, the backpack moves to a random slot on the hotbar regardless of whether or not the backpack was shown on the hotbar, or the legitimate slot before the swap. These issues occur regardless of any gui or menu changes, and the FancyMenu Customization Bar because nonfunctional when in creative mode.
