Hey, I've been getting this bug with the new Alien Races version and the dev of that mod says that it's another mod causing the issue called Harmony. Harmony had an update and has been causing a few bugs for mods that are using different versions of harmony. I was informed by both devs that some versions of the mod harmony inside other mods that I am using are out of date, so I wanted to check to see if you are using the correct version of harmony in this mod. So hopefully nobody else has any problems.
