My party just defeated Z'rell in Moonrise Towers.
Jaheira auto-joined before the fight. After the fight, we went to camp for a long rest. Jaheira stayed behind, saying that she will wait on our return.
On our return, indeed Jaheira was waiting. Before we could speak to her, she ran ahead and got engaged in a fight with a remaining warrior. In that fight she shifts into a panther. Then she ran a little further and just stood there. After the fight, she didn't turn back into her human form.
I replayed this part a few times. It seems not possible to prevent Jaheira from changing into a panther. She doesn't rejoin the party, there's no interaction at all. Shouldn't she join again before the fight with Ketheric Thorm?
