There seems to be some kind of bug that was introduced with the last set of patches that breaks the Hard AI(possibly others) that keeps their commanders from building anything at all. They will just walk to the destination of their first build location and just sit at it forever. This is happening now in 100% of the games that I try to launch in single player skirmish.
As mentioned in your other threads.... need logs: Reporting Issues: https://wiki.palobby.com/wiki/Reporting_Issues
Apologies on not providing the required logs in the report. Here are logs from the last several attempts at playing with AI skirmishs.
Need the server logs as well: delete all existing client and server logs start a local hard AI vs hard AI game on a simple system like forge upload the client and server logs for that game
