I constructed the basics of an pod for 3 kerbin plus an science laboratory. after that the game stopped responding before i could continue building. after restarting the came i can not enter the hangar. when i enter other buildings and exit KSP freezes up. the game did not send any crash report nor did windows recognized the game was not responding. the time in the game was continuing, i was unable to check what parts of the game where not responding. it occoured after firing an kerbal that was KIA Kerbal space program version: 0.90.0 Beta Saved game files: https://www.dropbox.com/s/4c4dho6cvg1o2z9/Tretron_save.rar?dl=0 output log: https://www.dropbox.com/s/zg3ui3kk9tjnkte/output_log.txt?dl=0 System info: motherboard: EVGA 780I CPU: Q6700 @ 3.0 Ghz mem: 4gb DDR2 videocard: evga 770 GTX Checked solutions: - Put the "CrewRosterFreezeFix.dll" into the kerbal space program/GameData folder and relaunched the game. i hope this problem is known and their is a solution for this.
