Okay so this one is something i have not run into before.

I am in a game 500+ turns super slow everything so a lot of time invested. I am at end game. AI has all the techs but for the last 100 turns or so they are still building old out dated designs. My game is modded so i usually just toss all my issues into game is modded i must have done something. But im not sure anything i did would affect this and past games with same mods worked fine.

Is the AI just being stupid building huge hulls filled with harpoons when they have nightmare torpedoes? Or another race has huge hulls and all the weapons but they are spamming medium ships with 3rd level kinetic weapons? I have not changed any blueprints or anything like that.

Its like every single of the 12ish AI races are at the end of the tech tree but still building garbage. Looks like i need to dump this 20 hour save but just looking to see if the more experienced people know why the AI would act this way.

Sry this really isn't a post looking for a fix per say just throwing it out there.
