It looks like theres nothin to do. I've copy that file (btw it was in disc 1) but nothin changed.
thats strange cos any other merchant not in random encounters work.
It seems to me, by the number of post in this forum that this game (wich is good however) is full of bugs.
The rest of the game run errors free.
But when i find any traders out of normal camp mission, the barter\gamble function doesn't show when clicking on traders, to get something have to steal or kill out everyone.
I got patch 1.27 installed.
