DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

I remember reading somewhere that there's a patch that allows you to prevent the map generator from creating slow roads. Does anyone know where to find this patch, because playing on slow roads is a real pain (and I don't think I'm the only one who feels that way). Sometimes I even spend my rest just because I don't want to crawl across the map like a turtle, which slows down development and, consequently, increases the game time (not significantly, but still).
