I really hate to say that - but BM is
broken atm ... as the AI is all to eager to offer intersettling treaties.
Especially "bad" are the Abbidons, which in my current game offered 30%trade/intersettling/full tech exchange(!) upon meeting them on turn 25 (+/- some). Judging from the score graphs, at least 1 AI got the offer as well, and accecpted it - what keeps them from becoming the MEE very effectively, while "in reality" they are!
Any way to fix this?
