Thank you so much for the feedback and kind words! I knew I probably missed a conditional check somewhere; I'll do some testing with the male customization and see if I can't publish a fix for it with the next version!
Edit: Looks like it was an issue with the breast size conditional check. Apparently it somehow got included in the "male" checklist as well, and it was kicking back an error because it couldn't replace a value that didn't exist on-screen. It's a simple fix and I should have it included in the bugfix list for the next version update!
