Hey guys,
I noticed this issue when warring with the Drengin on an immense Galaxy. We both started with the same amount of colonies ~100, but I took about 15 of his and never lost a battle. However, his military power is technically higher than mine since he has over a 1000 (mostly useless) ships to my 200 highly upgraded cruisers and transports. In spite of the fact that I've whooped his butt and taken over a dozen colonies, he still won't sign a peace treaty. Anyone else noticed this?
