FYI 4.5 beta AI is broken
Just an FYI for anyone who is playing the 4.5 beta. Unfortunately the AI's economic plans are not functioning at the moment. The scaling mechanism that they use does not work at all which causes it to heavily undershoot alloys and eventually, though its so bad it probably isn't practically reaching this, crash out entirely. Also the weighting system it is supposed to use seems to have been completely broken in 4.5.
I checked it against 4.4.6 which did not have these bugs and behaved nearly the same as 4.2-4.4
There is plenty of good stuff in the beta but if you are wondering why the Ai is somehow even worse than before, you are not crazy.
Hopefully it gets fixed. Figured people here should know since it isn't obvious unless you go and edit the code to observe the bug like I did. It is very annoying though.
