Just captured a 50m colony on Aruru, and to may dismay...

When I attacked it was a 50u colony (confirmed by Strongbad, and the left over pieces of my 60-odd ship fleet). For about 5 minutes after I owned it, it still showed 50u and the text "need 100u for factory" or whatnot. Then I checked in on it again later, the population is 0u and the text said it was an outpost.

I had a quick look at the code and I don't see why it would revert. If the population died during the attack it should have shown it. I'll have to pull the logs for that and see what went on.

I'm going to attack another colony in a few hours, approximately 30mu population. I will take screenshots before, during, and after, and will report back if it magically becomes an outpost like the last one.

Anti-climatic, perhaps, but it worked as expected this time
