You just broke the alt-bank checking function in 9.0.0 for classic wow:

5x ...\Wildpants\libs\Sushi-3.1-4\classes\drops\Dropdown.lua:136: Invalid data provided for :SetBackdrop
[C]: in function assert' ...\Wildpants\libs\Sushi-3.1-4\classes\drops\Dropdown.lua:136: in function SetBackdrop'
...\Wildpants\libs\Sushi-3.1-4\classes\drops\Dropdown.lua:48: in function New' ...\Wildpants\libs\Sushi-3.1-4\classes\drops\Dropdown.lua:57: in function Toggle'
...ns\Bagnon\common\Wildpants\classes\ownerSelector.lua:32: in function <...ns\Bagnon\common\Wildpants\classes\ownerSelector.lua:30>

Locals:
(*temporary) = false
(*temporary) = "Invalid data provided for :SetBackdrop"

Reverted to 8.3.8 and it works fine in the old version

I have the same issue, can't view bags from another character since last update (recently i guess last update)

BTW playing classic here.

Looking at it. Very unexpected behaviour.

Immediatelty figured out what it was. I'm an idiot.
