Not a bug, but a suggestion: Have you considered unblocking Jarrod's confession for the princess? Without the chance to do Jarrod-taming, she can't get the best ending for Revaire. If you are worried about accidentally getting the confession without doing the date, maybe limiting the romance increase for beauty in the WF could work.
If mc doesn't get extra romance for having 75 beauty, then there's no chance of getting undeserved confession.
