In the latest versions, the robot arms and masts in single player/space program are too affected by light winds to a point where it becomes near impossible to get anything done. This is the case for a lot of missions that require robot arms/and or masts/advanced masts. The constant shaking makes it seem like the robot arms and masts are made out of straws. Even just driving they can shake so much it seems like they could just snap and fall off any minute. (Very unrealistic stability)
