I would like to point out, that the lag-excuse would not hold up in a court of law.
Why? Because it happens at the very end of a match, and often.
That Mr. Stahl, is manipulation of games !!!
I'll guarantee it does not just happen at the end of games, for those experiencing lag, but it's much more noticable then, especially if you are winning when it happens.
That said, the site is working towards a more distributed network for live games where members will connect to servers closer geographically to them. That should improve lag fo a lot of members.
This is already in place for some games on site and I imagine it should be available for all games in the not too distant future.
I've been here for a while and, this does not explain the move mistakes for designated spots.
