Got this problem yesterday, and I restored the vessel from a save only 20 minutes earlier. Seems to work for now. I do use mods, but no gameplay altering ones. Is my log still going to be useful if this vessel decides to kick the bukkit again? Ok, so I saved quicksave #59, went to space center, switched to the Sun Orbiter Mk1 and the Kraken got it. I closed the game, reopened, loaded #59 and everything was cool. Same symptoms as described earlier: black game screen, UI visible but no navball contents. I can use ESC to get back to the Space Center, but it is also black apart from the UI. UI buttons don't respond either. I attached the output_log.txt and savegame files involved. Again, not sure if it is any good because I use mods, but hey, better than nuttin! If anyone is still interested in actively hunting this bug I can try doing it without mods. http://s000.tinyupload.com/index.php?file_id=40380621528233381603 KSP version 1.0.4 Platform: Windows 10 x64, installed through Steam Using -force-opengl command line Mods used (all managed by CKAN) [x] Science! 4.10 ATM x86 aggressive 5-0 Chute Safety Indicator 1.0.2 Contract Window + 5.3 EVA Enhancements 1.0.0 Intake Build Aid 0.6 MapViewPlus 0.1.1 Module Manager 2.6.8 Part Commander 1.0.2.4 Planetshine w/ default config -.2.3.1 Portrait Stats 6.0
