I read the thread about AI pathing in base attacks where they just hack where they drop and I don't think this is the same thing. Basically I've been informed of a base attack and the dropship approaches, drops off 3 soldiers and they just stand there doing nothing. I assumed they'd probably attack when I approached them but they don't react at all. They also don't attempt to hack my base. As this is a new game and I haven't had any dealings with the Zirax I assume my rep is 'Unfriendly'. I haven't got any guns on my base (it's the crashed ship) as yet so imagine if I did that would start a fight. Not especially bothered by this but I thought I'd post in case anyone else had the same issue.
The fix for this is now on the experimental branch https://empyriononline.com/threads/alpha-11-5-experimental-refinements.91665/
