Describe the bug
Guild Bank shows completely empty on first time opening after login. Clicking on a Tab will bring all item back to looking normal. Cannot Shift - Click to split Stacks in the Guild Bank. On first attempt to split you will get an Error Box. Any time after, during the same session, it will not except the split stack input. You can move the stack to your bag and split no problem. This problem will persist until you log out. Empty Guild Bank and Error Box will present itself again on next login.

To Reproduce
Steps to reproduce the behaviour:

1. On Guild Bank (Shows Tabs but no items)
2. Click on any Tab and all Items will show
3. Attempt to Split a Stack in a Tab
4. See error

Expected behaviour
Guild Bank shows empty.
Error Box when attempting to split stacks.
