I just did edit my last message to the nova thread in the discussion forum, but I guess it does belong here.
The nova mission contains a few bugs:
1) the planet info text displays the current system name instead of the one which went nova
2) after flying back to the nova system, it contains a sun, but no planet. I thought the sun should have gone
3) trying the planet info when the player is back in the nova system causes oolite to close (probably while trying to display the destroyed planets image?) - log and stderr do not contain any info
EDIT: Random Hits bug: After entering the system which went nova, there's still a space bar active!
EDIT2: After a short while the main part of the space bar is destroyed by heat, but some parts of it remain and the docking computer still does get docking instructions. However, when the DC should dock after the main bodys destruction, oolite does close itself without any hints in the log or stderr. Docking before the main body blows up is perfectly possible, and one can get new contracts
