I killed Ketheric and am ready to finish act 2, but the game won't allow a long rest, telling me "you can't fast travel". But this is wrong, I can fast travel to any waypoint without problem, including camp. And even in camp, if I click "long rest", it says I can't fast travel. So I guess something else is blocking. Do I need to talk to someone first ? I talked to Jaheira and Isobel after returning from the mindflayer colony, , but that didn't change anything. Does anyone have any ideas how to get out of this situation ?

For this run I installed some mods. Mostly face/hair/costume mods and also the party limit be gone.
