Hey no worries, great mod mate. This really adds another level to depth to the game. I have an update to my last post, the SPH doesn't encounter the same problem. Just the VAB so far for me, and also i've only managed to make the build clock for 1 spacecraft restart by pressing cancel edit and it was after simulating it (all in the edit mode). I'll try see if i can make it do it again, if not.. Well no problem.
