Just made two accs of mine Blast furnance ready! Love the script mate. I had to interfere twice, when opening the cupboard when Sir Vynn is in the room the script kinda breaks, he just keeps trying to open the cupboard but because you're just trying over and over Sir Vynn ain't leaving either. So its stuck in an endless loop unless you have break timings coming in to help you hop/reset. Lastly, it didn't finish the last dialog for The Giant Dwarf quest, I had to manually talk with that dude.
Hope this helps, but in general great script considering it's free. Would prob still pay for it tho
