This pops up as soon as i hit play in the editor and also in game when i select my map in skirmish. Is there a file i need to find to hunt down the error ? I followed the Atlas manual while i was setting up and as far as i can tell everything i have done is the same, re the settings , obviously not though lol I also had a look for my map here binaries\data\mods\public\maps\scenarios but could not find it listed as i wanted to upload the xml so someone could check it out, why would it not be there ? Love the map editor by the way, very nice to use, reminds a bit of the il2 editor cheers
