That's a peculiar one I haven't heard others encountering on this release .Any other mods with it? Added races, etc? Did you restore the backup files?
The script you had that bug with is about to be majorly revamped in this next release. Maybe they heard and are just excited for having variable dialogue options?
i have tried with only this mod and random portrait, and i still couldn't talk with any slaves. but i the only other mods i usually have with this is MEERD, random portrait and delayed portraits
i also have restored the backup files yes. i still have the download in a rar file, so i just delete the whole game and unpack it again.
edit : forgot to mention is still happens, even if it's only this mod on
