hi,
for the quest "the tea house" i can't talk to maryna after using the orbe to bring her to the ground.
i have been forced to look on youtube where whas auntie to hit her while invisible.

Yes she doesn't talk until you kill the hag. The hag is supposed to trigger a conversation when you come too close. I had to bug as well, so you are stuck killing the hag in a boring "fight".

That might not even fix it though. In one of my games I killed the hag and got a a quest completion but then talking to the girl crashes the game. That entire questline is just bugged.

The Hag never even appears to me. So how do I kill her? lol.

I got down to the bottom after she retreats, and I lower the cage and the girl wont talk to me, I go into the next room and no ones there, so I just left. Can't complete it.

Same here, hag retreated, I went through the dungeon until the final room, hag didn't appear so I freed Maryna, but I can't talk to her or anything.
