I fix it not reading as a map by unzipping the map folder and changing map id in moddesc.xml to Ardennaise and then it works for me.
@domberignon I tried, but it doesn't work... map id="Ardennaise" in moddesc.xml
I cant install the map...unzipped, placed in "mods", can see it between mods ingame, but cant start a new map in career...
@Azaluis Modding I did exactly that.
