The problem with the Orks comes from the saved empire file. In an older Version of the empire files, I had not changed the strategy settings in the saved empire file, only in the AI_Strategies file; the ship designs would call for one of the new strategies, but instead of looking for the new strategy in the AI_Strategy file, it would only look at the strategies in the saved empire file - ending up causing an error. Look for empire files dated 15 Oct 2002 (there was a point where the empire files were renamed in the TDM-Modpack from what they had originally been named, and you may have used an older set of empire files), and delete any older ones, or here is the latest Version of the orks from the AI Deathmatch:
