I'm doing a garrison mod for Attila. I did everything in building_level_armed_citizenry_junctions in the .pack file and even partially startpos.esf. Unfortunately, I reach to the point when I add a unit with ID number 2003 game crashes. I've tried different things but nothing helps. I add a unit using the "Duplicate" function in EditSF 1.1.1 and change its number to the next one (unfortunate 2003) and after saving the changes, uploading the startpos.esf file to my mod.pack and starting new campaign game returns to the desktop. Until 2002 unit number everything was going fine (I did a dozen or so factions). You know what the problem could be? Is there any limit to 2002 units in vanilla game?
