Sorry if this has been asked already, but I couldn't find the answer searching the thread. For some reason I can't launch manned craft. When I click launch, it takes me to the launch pad and all the staging is missing from the side and hitting space or even manually right clicking and activating engines does nothing. It seems if I use launch stability enhancers I can get the engines to activate by activating the engine, then releasing the clamp. As soon as the craft starts to fall the engines start firing but all the staging groups into one stage.
