I found a weird way to have finally access to Ulgoth Beard :
I started a new game (with TotSC installed now), in this game UB appears on the map (even if it's not reachable yet).
So i copied the file worldmap from this new game save to my real savegame and then I had access to UB ! Bad point though : all the zones i visited dont appear anymore on the map (eh it's the map of a starting game). Though in these zones, fog of war is gone where it should be.
Weird, annoying, but still better than nothing
