This happens twice to me. I usually copy an AI, let's call it "Reaper", make some improvements (always my hope) on the higher version and let Reaper MK II fight against Reaper (I like AMBIDEXTROUS for that). If "MK II" wins, I copy it and so on, maybe up to "Reaper MK V". I was pretty satisfied after some hours of improvement on my best AI. After a while it came up to my mind to let Reaper (the original) fight against Reaper MK VI and shockingly "MK VI" was totally defeated.
Reaper MK II hits Reaper
Reaper MK III hits Reaper MK II
Reaper MK IV hits Reaper MK III
Reaper MK V hits Reaper MK IV
Reaper hits Reaper MK V -- !!!
At the end of a row of improvements stands a weaker AI? How is that?
(Kanishka), but how can I explain this?Fixes break an AI more than bugs do
