Oh ok nevermind
I made the last updates to my offline install and all goes very well.
I went to one of my favorite spot in R'Oshanhnin Korvahkhn :
To go there you must turn clockwise around the whole canyon on a thin plane not much larger than the visual you see below my feet: Calena made that section solid thinking about me. She is smart, she anticipated that one of my first goal was to go find a way to climb there (...without cheat command, I hate using them unless there's no choice)
Now, I have to convince myself to solve the age but that's another matter...Give me something to climb on, I'll be happy...give me a puzzle to solve, I'll look for a walkthru somewhere
