It's because the gameplayobjects for Anctoville Coop/ SP are out of date and don't include the new Team SpawnPoints of Multiplayer Conquest. The devs have been adding new team specific spawnpoint to maps so depending on which team you are on you have a different set of spawnpoint at a flag. I'm often unaware when a mapper decides to do this so the gameplayobjects I set up for Singleplayer become obsolete and don't have the TeamSP (team spawnpoints) that are in the code for the map, resulting in the errors showing up onscreen. The easiest way to fix this If you don't plan on playing online mulitplayer is to copy the Gameplayobjects.con file from the 'gpm_cq' folder into 'gpm_coop' and 'sp3' folders.
