I'm working on a companion mod for the Final Mod Pack, but I'm hitting a snag - when I kill a Reptoid, one of the added alien races, the game CTDs. The same happens when I load a crashed UFO with a dead unit, leading me to believe that I may have a resource missing or misdefined, but I can't figure out what. The vanilla races act fine, both pre and post-mortem.
Any idea what I'm missing?
