I installed KIS a day ago and since then it keeps crashing after about an hour. When I revert to editor all the parts on the left are missing. Sometimes when I try to exit the editor the game crashes. I didn't had this issue before. Also the launch towers from the fasa pack are jumping after my rocket when it's asending. Sometime they even folow me to space.

Can you send me your KSP log file when the game crash ?

Sorry. I deleted it :(. It was the same meseage that you get when you reach the ram limit. The point is that i didn't even get to 2 GB. Normaly the game crashes when I reach 3.5 GB. The install was not just stock so maby I had mods that are incompatible with kis. I created a new build using ckan and now it's working properly. I had some crashes but no missing parts or textures. :)

RE: Launch tower issue

This is a known bug that's unrelated to KIS. https://www.reddit.com/r/RealSolarSystem/comments/3auw07/launch_clamp_bug/csg89n0
