Apolyton Edition: City Improvement and Wl Limit

[Carolus V.]

Hello everyone.
I have a question: Is it true, that there is a City Improvement Limit of 64 or 65 Buildings? If so, what good does the MAX_CITY_WONDERS and MAX_CITY_BUILDINGS flag in the const.txt.
Btw, if someone is interested why the AI spams out settlers, It seems as if it has something to do with the BuildSettlerProductionLevel 0.00 entry in the strategy.txt file. At the moment I can´t confirm it for sure ´cause I´m in the middle of playing my latest game, but as soon as I start a new one I will know for sure. Anyway. BUT the AI spamming Settlers like there´s no tomorrow is the cause why the game crashes at some point, either because the AI kills itself creating a settler in its last city or it doesn´t respect the Government City Limitation and settles and settles ....
However, it would be very nice if someone has knows how this City-Improvement Problem could be solved, or knows something about how the two afore mentioned flags work.
Thank you in Advance.

OK. 32 Viewers don´t know how this works. Well let me ask the other was around: Has someone, somebody ever tried to implement more than 64 City Buildings (a.k.a. City Improvements)? If so have you done this in a vanilla AE game or a Mod?
As far as settling is concerned, the AI spits out settlers after settler and creats one city after the other without any respect to the STRATEGY_TOO_MANY_CITIES entry in the strategy.txt. The thing is, the AI does it until it has so many cities so the whole empire starts to revolt and on the next the game crashes.
If someone knows anything about this, please let me know.
Thanks.
