Got this on Jarrod's ending:
There are also other bugs: I'm playing a princess who managed to convince Gisette to step down peacefully, and I choose to follow duty earlier. When I saw that there's peace in Revaire with Queen Sarya, I expected that Arland would break the betrothal because there was no gain in marrying him now. But the description of Arland's reaction to the match acts like nothing happened. The reaction happened twice, seemingly one for duty princess and one for freedom princess.
Then Jarrod's ending process like nothing happened in Revaire until the game-breaking bug.
