I am unable to (re-)assign the button B in the key binding / controller settings. When I do, after pressing the button (B), I see the window that asks whether to replace an existing binding of B for a very short moment before it closes. The whole settings window closes, too. This happens even if the B button is not assigned to anything anymore (at least according to the settings that I can actually change).
I am aware that pressing B usually closes the open window. In this case however I would expect the window to stay open. It is as if the one click of this button is used twice - once for entering the button I want to use for the chosen ability and once for closing the window. This even happens when I try to press the button for as short as possible. I can’t rule out that my XBOX controller is actually sending the button click twice, however. Is there some way to check this?
Are the key bindings exposed as a config file in my file system somewhere? Maybe there is a workaround to change these settings?
