And as a cake topping, there's some weird interconnect between the data on the server (or so it seems), because when I change some binds, others get bound again (previously successfully unbound).
Or just when I thought I at least managed to unbind all base binds I didn't need, I tried adding addon binds only to have all of them deleted upon reloadui.
That's all with resetting to defaults first (which seems to wipe all addon binds too
with the exception of one for pChat that just cannot be removed for reasons beyond this dimension)
This crap is seriously bugged
It's stuff like this that makes one question whether he should have bought ESO+ again)
