I just bought the game being an avid fallout fan but i became very disgusted with these glitches i always find.

I am doing the quest "They Went That-a-Way" and i am trying to find Beagle's Journal from his corpse to find information on my attackers.\
This is what happened.
Well first of all i saved him. I asked him to follow me. I went upstairs and he was there but after killing some people and going downstairs he wasnt there anymore.
Ive searched upstairs and ground floor for a body. Ive also searched Primm and every building and every square inch of the town hes just not there!
If this could be fixed that would be great.

Also my quest marker points to Bison Steve Hotel when nothing is in there anymore

Must be one of the many annoying bugs in this game I guess your only option is to keep looking unfortunately I think that's all you can do.

The only way that you could reliably *fix* this is to re-load an old save, and if you haven't a save from before I implore you, save, save and save again, on multiple save slots.
