Due to a wired glich, I'm stuck in my current endeavor to collect relevant info for all quests and track monster drops along the way. Something keeps corrupting my saved game, leading to Hell Hounds refusing to die properly and leave a drop. It might be triggered by missions I completed, since it persists with reloading the same save, but doesn't occur with an earlier save, while reappearing when I progress naturally with this earlier save.
I might be able to resolve it, but in the meantime I have to put my current work on hold. Though, if it doesn't work out or takes too much time and effort, I don't think I'll have the motivation to continue :(
