The title speaks for itself. The door controls are great, but cannot be rebinded (which on the QWERTZ keyboard is not great at all as Y and U are half the keyboard away from each other).
To precise it: You can rebind it in the menu, but the game itself doesnt recognizes it so you always have to use Y and U to utilize that feature. I have a QWERTZ-Keyboard and tested this after I deleted the "Saved"-folder in my documents to make sure that my files arent corrupted. But it didnt change so it is definitely a bug.
