While I was doing a lunar mission, I was switching to another command pod NOT IN MAP VIEW, and there was no loading screen, but when I switched crafts IN THE MAP VIEW, it had the loading screen, then it said:
SimpleRockets2.exe is Not Responding
-Check for A Solution and Close the App
-Close the App
-Wait For it to Respond
There shouldn't be a loading screen if the craft is close enough (but its got to be pretty close).
Do you have any crash folders here?
%APPDATA%..\Local\Temp\Jundroo\SimpleRockets 2\Crashes\
If so, could you zip them up and send them our way so we can investigate the crash? You can upload them here.
If the game crashes, the crash folder should be created automatically.
