When I go to the multiplayer lobby with my modded RTW, I see all RTW games as "not compatible game data", and cannot join them. Obviously that is good, but when I tried to play with someone who has the same mod, it still said our data was not compatible. That means something must've gone wrong when passing the modded files to him.

Does anyone know what files are compared for compatibility ? I remember a while ago my mod was considered "compatible" with vanilla RTW games, even tho it already had completly different units and stats. I just can't remember changing what file caused the mod to become "not compatible".

I'll be looking into it myself, but if someone knows, that'd be nice. Just so nobody asks: I'm using v1.2 and I'm not using a "no cd crack" or something.
