On some naval maps the AI just builds T1 subs until it hits unit cap. This is especially true if there's a section of water where the subs are trapped. Is there any way to avoid this? In this game 30% of unit cap is taken by T1 subs at 25 minutes: https://imgur.com/W5Ytb01.
Also, does disabling nukes prevent the AI from working properly? I posted a year or so back and you fixed it. Recently it seems like disabling nukes makes the AI stop building most experimentals. UEF seems most affected by this change. Aeon plays normally with nukes off.
