I had a problem getting my maps to work in FfH2. It turned out that regular BTS maps have 18 teams and players (just blank entries from 0 to 17) but FfH2 needs 35. Copy this into the map file in the right place:
You might also want these:
Code:
Randomize Lairs=true
Randomize Unique Improvements=true
Randomize Goody Huts=true
EndMap
and from what I've seen these additional teams and options won't keep the map from being used in vanilla BTS.
