First of all, SPOILER ALERT - DON'T KEEP READING IF YOU HAVEN'T DONE THIS QUEST.
Now that that's over, I'm at the last(?) part of the Jake's Murder Quest, where I need to reveal Evelyn's lab with the spell from her house, thing is, I think I sold it or something.
What the heck do I do now? I need help!
(Note: Reloading the game is NOT an option. I've spent too much time playing the game past that part that I'd rather just stop playing the game then reload basically everything.)
I'm willing to use cheats to modding tools to get the item back into my inventory at this point.
