I don't know if anyone else noticed this yet, but I think I found a bug in how the AI uses fleets.
I was playing the Terrans and conducting a raid near a Drengin held planet. I knew it might be a suicide mission because they had a huge fleet in the planet's orbit. Sure enough, the next turn, they dispatched nearly their whole fleet. They didn't attack my fleet because I might have been just out of range.
One thing I found perplexing is that the ships they sent out didn't merge into a fleet. All of the ships appeared in the same hex, but individually, not as a group. I was able to take advantage of this and destroy their ships, one by one, like ducks in a row.
So it seems that there's a bug when an AI dispatches multiple ships from a planet. When I do it, the ships automatically merge into a fleet, provided I have enough logistical points. But when an AI faction does it, the ships become separate entities and do not merge (at least, not until the next turn). Anyone else notice this?
