Ok, the beta feedback section seems to have pulled a Houdini, so I assume bugs should go here
So there are a couple problems with the AI using envoy cruisers. Since it is still a beta, maybe these are things that haven't be programmed yet, but I thought they should be mentioned, just in case.
1. The AI builds way too many of them. I didn't count exactly, but it seems that they build at least 1 for every other player in the game, when something like 3-4 would work just fine.
2. They never leave the home planets of other AI players. They'll leave human homeworlds, but they just sit around AI ones.
3. They do wierd things when they are on your planets when you finish researching the one that allows structures to target envoy cruisers. They'll just jump back and forth between two planets if they both have defences. And then they die, because they just go to the same two planets until they get killed.
