[color:"red"] Are you sure you reloaded the same save that you substituted the file in? [/color]
Yes, I am sure. I checked for a couple of times when editing.
[color:"red"]Did you exit the game to do the file swapping, or just alt-tab out? [/color]
Yes, every time I edit the data file, I exited the game.
[color:"red"]If you re-open the data.000 file that you edited and check the coordinates, are they the new values for inside the guild? [/color]
I checked. Hex editor save them as I edited. I went up to tavern and standing near Rob saved my game. Then I opened the data file with hex editor and my coordinates was the same A0 1C 50 8B... Maybe I edit wrong vaalues?
Here, I copyed a piece of my data file with the new coordinates:

In this case my hero still standing near the locked door.
Also I deleted the \Divine Divinity\Run\Dynamic folder as you said...
