Just some behavior I've been observing with the AI. They are utilizing economic, mining, & archaeology modules - but not defensive/offensive modules in any way. This is some 350+ turns into a game with lots of starbases and not a one of them has a military upgrade (insane map, probably 15+ players, genius to godlike AI).
They will send their constructors to a base, park inside it, then do nothing for a few turns then leave and go to another starbase (without upgrading modules). Sometimes they just repeatedly load up the same starbase, que out, then go back inside. I think they want to upgrade the starbases, but have forgotten how?
I know I've seen the AI utilize offensive / defensive upgrades before, so I think this is new. Can anyone else confirm and post what size map they are seeing it on?
If you do not want to use god mode, or the fow cheat, an easy way is to go to the diplo screen and hover your mouse over the starbases in their inventory to see if they have completed any military upgrades on their starbases.
It's of course adding to the turn times, to have so many constructors not building just traveling around the map without purpose
