I had the same issue, and at least for me, I'm pretty sure it's due to a bug with the Chota plant pet. After the scripted loss to the Queen Orc's bodyguard, the party leader somehow becomes the Chota plant. Like in every sense, Kunnai would follow behind the Chuta walking around, in the top left it both said Chuta and had the its picture, and going into the character menu the Chota was in the first slot. I fixed it by teleporting back to the room in the Dryad Kingdom and returning the Chuta, then asking it to follow me again. So I think because of that bug, when fighting the Queen Orc you technically have the stats of the Chuta. Because after my little fix, I then the I easily won the fight against the Queen Orc.
