well shields appear in ALL of your new (BETA) ai research files
Firstly....
AI State := Exploration, Infrastructure, Prepare for Attack, Attack, Secure Holdings After Attack, Incursion, Prepare for Defense, Defend (Short Term), Defend (Long Term)
Tech Area Name := Shields
Tech Area Level := 10
Tech Area Min Percent := 25
and then secondly...
AI State := Not Connected
Tech Area Name := Shields
Tech Area Level := 5
Tech Area Min Percent := 25
These are the only 2 mentions of shields in each of the research files. I think this is also true in the defalt ai research file
I think this is what is causing the problem with them researching shields
I was gonna see if i gave the ai in my game all my propultion tech up to gravametric engines, if they would start building big ships, however i just deleted all my save games for old ai b5 so i could start afresh with new ai about an hour ago

oh well!
Also is there any way u can make it so the ai uses population transports and ships pop to other planets as it would make them alot better as there colonys otherwise take YEARS to build the simplist of things.
