I have noticed when I open the Transmog menu it stops all my keybinds from working. This includes movement and default keybinds. Closing the transmog menu or swaping to a different tab also allows keybinds to work. I am unsure what causes it. It seems to happen randomly.

I would like also add that opening tmog menu (and maybe even associated collection tab) turns to white range keybind indicator on spell buttons, which is defaultly red while out of range. That makes impossible then to differentiate if youre in range during combat or not, as in both in range/out of range situation the indicator is white.
