I was playing the latest release build you have up for download, and everything was going smooth til the AI just stopped working. They went completely passive for no reason, harvesters sat idle, units and structures were put on hold, and units just sat in place. And it wasn't just a specific AI setting, it was all of them, both my allies and the enemy at the same time.
Erm... Trying to attach debug log and replay but it is either too large or an invalid file to attach here.
We've identified that there is a bug somewhere in the AI harvester logic, should hopefully be fixed in the next playtest.
We would be very interested to see the replay, which would help confirm whether this is the root of all of the reported AI problems, or one of multiple issues.
Just played a dozen or so rounds on the new playtest you released today, the AI is still acting funny. At random times the AI will just stop dead in its tracks and do nothing. I watched one on the last match and it was crushing a nearby enemy and then all of a sudden it just sat there and didn't finish the job. I had a mini squad come after me but the army it massed froze in place. Here's a replay and log:
