Okay! How can I share a file with you? From what I can see I can't post it here.

Okay, the issue is resolved. The dialog windows did pop up where it shouldn't next to fireplace, but the quest works correctly. For anyone having the same problem: I've mistaken the cave for the cave in the well. You should go to the cave where green slimes where. I wanted to tp there, but it was blocked so I assumed the location itself is locked. It's not but you have to go there without teleporting, that's all.
