My load was a skirmish 4v4 playing mordor on the Tournament South Downs map (with all the factions expept erebor). The error message is "Error loading game C:/user/name/Appdata/roaming/my the lord of the rings, the rise of the witch king files/save/saved game I.BfME2Skirmish".
Also, the AI of Dol Guldur as an allied is kinda weak, it spams a lot of builders but doesn't expand it's terrain.
