I think I screwed my game over too, and I'm way too far into the game to restart.. I killed Zombie Jake accidentally from AoE and at the time I didn't think anything of it. I actually thought it was a scripted event as he rose up & attacked me straight after I killed Evelyn.
Naturally I kept playing many hours later, I'm now level 9 and have just killed Braccus and I still can't complete the Mysterious Murder and Counsillor's Wife quests, due to doing many of the quest events 'out of order'.
Surely Larian can help us out here, give us a console command or fix to respawn Zombie Jake? I was having a blast playing this game up until now
