Hi, I am using fedora 20 and 0.23 was pretty stable there. Unfortunately after update to 23.5 KSP is crashing almost every time when there is a scene change. I have the steam version of the game and the issue occurs with 32b and 64b binary. Also I have tried install clean version without any mods and it also did not help. But here are the mods which I am currently using [lnykryn@notas Kerbal Space Program]$ ls GameData/ DamnedRobotics LTech MechJeb2 NASAmission OrbitalConstruction Redux Squad I have uploaded KSP.log and some other logs here: http://lnykryn.fedorapeople.org/misc/ksp/ If you need I can also provide you a coredump, but it is quite huge (1.6 GB).
