ksp 0.23, remotetech2 1.3.3 i'm not 100% sure if remotetech is to blame, but here goes. Getting randomly NullReferenceException in debug log, when switching "switch to" diffrent vessel in map. (and can't control vessels anymore, need to quit ksp and restart -> resume) ksp.log shows [EXC 04:07:14.511] ArgumentOutOfRangeException: Argument is out of range. Parameter name: index and output_log.txt: and that seems to lead for alot of "NullReferenceException" errors in debug log.
