Did you disable the original Random Events that gave Wilbur (a Janusk lookalike) and Kodrin (a Kiergann lookalike)? I created new versions of them with new InternalNames, but I'm not sure if they are showing up. I have a Core file replacement that replaces those random events, however if you have disabled them then my replacements would be disabled too. I'm pretty sure they showed up with the XtraDeconstuct skills, which means my ones would be replaced.
Thanks for all your help today!
