I teleported to Khorinis and then back to Creole, and a dialogue with learning a demon language appeared. When I entered the conversation with Creole again, the dialogue was gone.
Something's not right here.
I learned the language of demons, but it's a strange thing.
PS
A colleague from the forum had a similar situation with a bag of ore for Snake, he had to teleport to Khorinis and back three times. Only after the third time the place where magic ore was hidden appeared.
@Liker, I don't know if this is a game bug, but I just wanted you to know about it.
