Crew Insurrection Bug?

[tmcc]

In the current game I'm playing of the SEV Demo I just a very weird occurrence. The first race I encountered was the Abbidon, home system only two sectors away. After some 20 ish turns of battle I completely eliminated the Abbidon (never got them to surrender). Now 25 turns later I suddenly get a message that one of my ships has mutinied. When I go to check it is now flying the Abbidon flag. Interestingly enough the ship is in what used to be the Abbidon home system.

Is this a bug, or is the program just selecting the Abbidon flag because it's no longer being used? If it's just flag selection I think the code should be modified to exclude any of the race flags for races that are in the current game for a general crew insurrection.

Also there was no good reason for the crew to revolt. They were fully supplied orbiting a "jubilant" world with six other ships, no current wars and far from the front line. All in all pretty good duty.
