Possibly a Glitch?

Oct 01, 2010
A while ago I was searching for some sidequests that could support me against the white buffaloons for their meat. I found a vampire in the mine of cooper's roost and he wanted to me to rid of some bloodbats in exchange for silver. I thought this would lead to a vast amount of wealth, but I after that my comrades spoke of "silver bullets" and a 'Duck of Death". I realized I was in an upcoming main quest, and I remebered the fuss about the meat. Was this intended or not? Please relpy.
