Point Lookout Bug (?) ~Heart Of Blackwell~

[Frankenstein's Raven]

In Point Lookout I was doing the quest The Heart Of Blackwell, I found the book and I went back to Marcella's tent and didn't find her dead or alive. I waited for in game hours. I was attacked by the smugglers, but they were outside of her tent. Becuase I haven't done this quest in what felt like an age, I wasn't sure where she was. I later learnt (from the Fallo9ut Wiki) that she is killed by the smugglers that attacked me, but I cannot find her corpse, nor the holotape. Is this a bug? Where is her corpse? Can I fix it? Do I have to go back to an eariler save?
