Ok, I see why that workaround works. But, the more I thought about it last night, the more I'm convinced that "Electronics" doesn't belong in the 1920s skill set. It's clearly marked as a "Modern era"-only skill in the Keeper's Rulebook. In fact, the description of the skill says: "For troubleshooting and repairing electronic equipment. Allows simple electronic devices to be made. This is a skill for the present day—use Physics and Electrical Repair for electronic developments of the 1920s." So, I really think that skill should be moved to the "Modern Era" skill set. Your workaround is good for the rest of the "Uncommon" skills but that one really doesn't belong. And, thanks for looking into the Lore skill! Nora C. said: Saul J. said: To have both the non-era skills and Uncommon skills greyed out in the same way makes it confusing. For example, Electronics is a non-1920s skill but it appears on the sheet greyed out. Or maybe that should move to the "Modern" setting where it belongs? That would resolve the issue too. (See p. 98 of the Investigator book showing that Electronics is a "Modern Era" skill). Thanks, again! I see! The rationale was to keep them available as an option to address use-cases 2 and 4 in your post here , but my (perhaps optimistic) expectation was that the GM would know which uncommon skills needed to be turned on for the characters they were working with. It won't be as simple as just marking the uncommon skills, since I believe at least a couple sourcebooks introduce other uncommon skills for their eras. I can't promise much beyond "I'll give it some thought" for now, but I just tested and confirmed a work-around that seems to address your use-case in the meantime: If you have the era set to "Show All," then hit the "Toggle All..." button so that all the skills are showing, and finally set the era after you do that, the uncommon skills that should apply remain visible. It's not perfect - I can imagine it might get a bit taxing if you're making more than a handful characters in one sitting - but it works. As for the Lore issue you raised; I've isolated the cause and I've made a ticket that I'll endeavour to get out the door ASAP.
