Jessie would not show up if you start a battle during her quest, and that's the case for every combat encounter there.
Also missing the " at the start
Jessie quest would mention your companions even if you didn't bring any
When trying to uncurse Kythie, if she has high lust the game would mention four busty muscle-girls being in the room, even though Eirina, Kythie and Tethys are only three and I wasn't playing a girl either
Extra " in Kythie's dialogue when you leave her in the garden
If you sent Cait to deal with Kythie then went together with her to visit the princess, the game would act like this is the first you and Kythie met, even if you have fucked her multiple times beforehand and exhausted all her dialogue
The Champ would also inspect Kythie as if they haven't seen her before when you send Cait
Dialogue going down a line in Kythie's and Cait's Assfucking scene
Either that's an extra " or there should've been an " before You Know
