Page Not Found when vote is the one that promotes

Ok dont get made at me for my last post..this one is serious..

Just testing on my site, i have the amount set to 3 votes to get to the front page. Now if a node has 2 votes and I vote on it (from a teaser), then press the node title to view the full node, you get a page not found. the path is fine though because if you navigate to it again its there.

i am using pathauto but that doesnt seem to be the problem..
