I am reporting this the third time now (once in alpha, once in beta1 and now in beta2)
The UP and DOWN keys are ALWAYS bound to move forward/backward respectively. If you bind another action to UP and/or DOWN arrow, it will perform both actions, e.g. if you bind CROUCH on DOWN arrow, you will now always CROUCH and MOVE BACKWARDS.
Please, can we have a fix for that? I dont really enjoy playing the WASD setup.
