Oh, that's really strange, hm...I haven't come across that bug before. I've attached a save file that starts on the line right after this one here, just download and drag it to "User/AppData/Roaming/Chattercap/Kanau" (you might need to enable hidden folders).

Other than that maybe try re-downloading it? Possibly some of the files got corrupted during the download?
