after few latest patches,
binding combined modifier keys didnt work on current game version.

normally I would tend to bind ctrl+alt for character perspective change.
now, when I try, game accept ctrl+alt input for binding,
but after click apply button, "ctrl+alt" just flipped "ctrl, alt".

this means not a combined, just seperated two key for action and actual game input also.
alt is perspective change and ctrl too, not a alt+ctrl combined which I actually want.
