Not sure what to think about this, a friend of mine says a party came to his door canvasing for their candidates, he said he was voting for the other party, and the canvassers left. A few hours later, he gets a door hanger from the same party encouraging him to vote for their candidates but... the precinct information is wrong.
He hopes it was an honest mistake, and having worked on campaigns before, I can definitely see a volunteer getting the wrong pack of pre-printed doorhangers (personally, it's for that exact reason that I wouldn't print precinct info on handout literature, I would have information on where they could look up their precinct.) It's probably nothing, but like I said, I'm not sure what to think of it. I usually give the benefit of the doubt on this sort of thing unless there's a pattern.
