Well, not exactly a bug, but a missing feature in this game. And I think very important one.
In game there plenty controls can be changed for the player (GUI, Hotkeys,Interaction,movement), but there no options to change camera controls. I have broken down arrow keyboard and I can't move my camera in particular direction. Player should have option to change camera controls buttons, because with out this option some players wouldn't able to play the game with pc issues/limits like this one.
