Just some bug, after rescuing the noble's daughter in the north she slept in the bed that I couldn't enter then I asked the inn keeper to let me sleep then the noble's daughter disappeared from that room. Then when I check back again the previous location of the enemy where I found her, she was being tied on the table again by the Goblins. Then the Goblins kept respawning no matter how many times I kill them.
I think this bug was caused by talking to Ivan again. There was some trigger in his dialogue that I missed. I'm pretty sure I fixed it in 0.56.75 though.strange, i could play through that part without any hiccups. well i didn't check that cave twice, at all.
