Well, it seems it didn't like a single change - me adding the possibility to build FARM improvement on desert and tundra.
But it still doesn't quite work. I can't get your national wonders to show up. Instead, I have broken leftovers of Wondrous Wonders (which is weird, since I disabled and afterwards deleted WW from mods folder) like LOC_MAGIL_NATIONAL_EPIC_NAME and others. Gotta try deleting cache, see if it works....
EDIT: it does not. Still got faulty national wonders..
also from database.log:

which means that for some reason, parts of the mod do not work - like the sql querry that should've added the column in the first place.
