Update: The key has now disappeared as well from his stool after closing the game and reopening it...

Apologies for the format and the lack of image. I had to post this on my phone as the desktop version of the forums wouldn't post anything at all, so figured it was best to get a half decently explained error log out than nothing at all.

A Rivalry For The Ages Quest Bug (The Sequel) Hello There, (Apologies for the block of text) So I started the 'A Rivalry For The Ages' Quest, yesterday, as soon as I built the Museum. I also built the Seer's house straight after. Once I'd done that I decided to go for the London Alliance, cause 'A Rivalry For The Ages' was down there so I'd have to head there anyways. I went down to Maximilian's house and he wasn't there. No problem, I decided to go ahead and do the London quest line. Once that's all done and dusted I went back to Maximilian's house and he wasn't there, again. But there was a few random npc's around the area dead after the whole burning city situation (not sure if this is normal either). Waited around a few times and he still didn't turn up, so I went through the whole Asgard storyline picking up all the tears or Ymir and all doing the Mysteries, etc... Went back to Ol' Max and Low & Behold he's now spawned... But as one of the random npc corpses I mentioned earlier. Didn't think too much of it as his key is still on his chair, but now the game tells me I can't pick it up as he's 'Not Distracted'. Not sure how being dead doesn't class as a pretty big distraction, but nevertheless it looks like I'm unable to complete this quest. P.S. Before it gets asked, no I don't have an earlier save as I only made 13 save files and just overwrite the oldest one when I need to make a proper save.(using a quicksave in most other situations) Pretty sure he's not meant to die, but he doesn't seem to respawn either (probably owing to the fact he's not meant to die)... I tried to attach an Image, but it won't work for some reason.
Any assistance would be greatly appreciated.
Cheers in advance
