Update: -force-opengl = lots of graphical glitches for me (only bottom left quadrant visible) RAM checks out (Memtest86 v6.0; 6 passes, windows memory diagnostic) with 0 errors Tried the fix for freezing from fired/dead kerbal bug; no luck, still freezing (no entry in persistent.sfs for rescuing any kerbal, stock patch did nothing) Rolled back video drivers to 770 disc original; no luck, still freezing Reinstalled 347.52 video driver; no luck, still freezing Reverted to KSP version .25, everything works perfectly.... (copied to different hdd so i can still play; yay got my digital crack back! well, kinda...) Re-updated to .90, game freezes after about 30 sec in the VAB.......... RABBLE RABBLE RABBLE!!!! the following is the only NullReferenceException in the new output.log, and was from when the game froze: deleting part liquidEngine (Filename: C:/BuildAgent/work/d63dfc6385190b60/artifacts/StandalonePlayerGenerated/UnityEngineDebug.cpp Line: 49) NullReferenceException at (wrapper managed-to-native) UnityEngine.MeshFilter:set_sharedMesh (UnityEngine.Mesh) at SpriteMesh.CreateMesh () [0x00000] in <filename unknown>:0 at SpriteMesh.get_mesh () [0x00000] in <filename unknown>:0 at SpriteRoot.Delete () [0x00000] in <filename unknown>:0 at SpriteBase.Delete () [0x00000] in <filename unknown>:0 at UIListItemContainer.Delete () [0x00000] in <filename unknown>:0 at UIScrollList.RemoveItem (Int32 index, Boolean destroy, Boolean doEasing) [0x00000] in <filename unknown>:0 at UIScrollList.RemoveItem (IUIListObject item, Boolean destroy, Boolean doEasing) [0x00000] in <filename unknown>:0 at UIScrollList.RemoveItem (IUIListObject item, Boolean destroy) [0x00000] in <filename unknown>:0 at ApplicationLauncher.RemoveApplication (.ApplicationLauncherButton button) [0x00000] in <filename unknown>:0 at ContractsApp.OnDestroy () [0x00000] in <filename unknown>:0 (Filename: Line: -1) Any other ideas anyone?
