Hos to do it? I have edited the buildingsinfo xml file (i think that's what it is) and set the obsolete tech tag to NONE, but they still go obsolete at Scientific Method. So is there another place i have to edit them?

A few buildings (Monasteries among them) are "special" :dubious:
Hence look into Civ4SpecialBuildingsInfos.XML as well.

Thanks! Sadly im not at home, and wont be until Tuesday, so changing this up is going to have to wait a while.
