Hey guys, kinda noobish here, but I have a problem with control of my vehicle using mechjeb. I installed the mod a while ago and made several flights using it, but then I started it and tried to launch a rocket, but I found that mechjeb had no control. It seemed to be trying, but the fins didnt move, the stages didnt decouple, and the throttle didnt move. It is like it lost its physical control. Anyone know why? cant find any other explanations.
