I answered a question over on Gaming - and got a downvote (fair enough - it was a wrong answer in the end).
But, it appears that the single downvote has been counted twice against my reputation - once for each tag the question was tagged with.
Is this a bug or a feature of the SE engine? Does this mean upvotes are also counted more than once? (Although, that has not been my experience so far)
