You may all of seen the pictures from my map I am working on, well I just pressed Ctrl+S to save the level and my computer crashed, ah no problem, I though. restarted and now 75% of the map has dissapeared and has turned into hundreds of "invalid solid object".
This is nearly a weeks work here, has anyone got any idea on how I can fix this?!
I had this happen before on another large map, and I didnt find how to fix it then, please please please someone tell me they know a way to fix this!
