Last night I finally made it to the mun. Turned in my science for more equipment at the R&D Center. After that I even made a new ship with the new parts. Log in today, continued to make more ships using the new parts, etc. Failed some launches, normal stuff. The stuff I did today was not progress so I wasn't worried about saving so I just X's out of the game since I had it in windowed mode. I load the game back up and all the science I had is gone, all the parts are gone BUT the ship I was making with the new parts is there. I can load it and such. I'm really confused. What I have figured out however is the game is loading my last F5 save I did last night before I began my orbit back to Kerbin. All my science is there and I can just redo that to get it back. However I still would like to know if I can fix this instead of redoing this orbit? Isn't it odd that my ship with the new parts can load but all those parts and the science tree is gone? BTW, new to the game...bought it three days ago and LOVE IT! Not even a science guy or space but I have become very interested in space now!
