I would of highly doubted a newly integrated system of any sort to be without a few minor 'glitches'. To highlight another point, if you disconnect/log out as you receive your score then you are stuck in the firing line :-/ This is not publicizing this fault but just making others aware of the error.

However above all it is recommended to test your marksmanship skill while you are near enough to the router or in the nearest empty room, as this will hugely decrease the chance of a bug affecting you.
