I already posted this in the bugs/technical subforum, but I thought that maybe someone here may have some idea.
I reinstalled Oblivion under 64bit Win7 and have some problems with Battlehorn Castle DLC.
It installed just fine and I was able to liberate it, but for some reasons the quests/scripts don't seem to work right.
E.g. the dwemer forge provides no bonus and I can't create trophies - I can deliver animal parts, but the trophies never show up, no matter how long I wait.
So I thought there could maybe be some conflict between mods?
I'm using the latest Shivering Isles patch.
