Is this happening to anyone else? I ask because I don’t see any posts about it. The last 3 or so competitive matches I’ve been in all closed due to a “server error.” Always when I’m winning too smh 
When I look at them in the history it says its a draw until I play another game then it disappears
its a server close exploit. its able to be done at any time but you have to be in hero select.
Happened to me too, twice. Just about to win, is it really an exploit?
yup, pretty much exactly
