Very nice mod! I set this, in a nice spot I think, up. Needs to be expanded, though. Here are some bugs I noticed (I know that this is an early release): 1) The Thermic Rocket Nozzle works without a working reactor (no antimatter on the craft) - simply use action keys to release the Launch Clamps, fire the engine manually and you are good to go.. almost. The craft then has a huge tendency to go sideways if given any input, straight up works fine. (If you hit the staging button everything goes back to normal) 2) The Braytons produce energy without a working reactor (no thermic energy, of course, stored). 3) If you use more than one Antimatter-Tank and another one is empty, the reactor shuts down. (Had the middle one (full) and the biggest one (nearly empty, 1,3 units stored)). Took me a while to figure this out - set up from above; one of the sections was already there) 4) When the throttle gets locked, because of a deactivated reactor, it doesn't unlock when you reactivate the reactor. (You have to go back out and in again.) I think that were all of them. Keep up your good work, I'm eagerly awaiting your next update.
