It looks like when making a scholarform singer, the Forms of Wisdom extra skill and the first Erudition skill are linked so they both pick the same thing. (Changing one changes the other too.) I’m told by Brotherwise that’s not the intent of the rules, so being able to set those to different things would be great!
Thanks for letting us know about the issue. It should be fixed now but it will end up resetting skill choice.
