Thanks for the console pic! I can troubleshoot and fix that talk error now and will have it fixed by the next update.
I don't think that's my mod, to be honest. The only thing my fix changes is 3 daily events that call races incorrectly, not anything in the constructor. I don't replace anything within the mod that should change race spawn rates either. Are you using v5.22 or v5.22a? He released an update right after that said he fixed the races in the changelog.
Note: If you are using v5.22a, don't use my "replacement" fix anymore. Haven't looked at how he fixed it yet, may have been the same way, but either way it's supposed to be done already.
