There's a bug if you convince the Revaire royal family to step down (without Sayra marrying Jarrod) + romance Jarrod yourself.
First scene in Revaire ending is the royal family stepping down and Sayra becoming sole queen...
But then when you marry Jarrod, he is still crown prince and you become crown princess (before murdering him or getting murdered).
Interested to see what would happen if the bug was resolved and you romanced Jarrod but he was no longer a royal in the end...would you still get married...and would he still murder you? Lol
