This is a guy who disconnected
from a long ladder game, which I though I was gonna lose, cuz
my initial hydralisk offensive didn't work, and he had a bunch
of bunkers. But I sent a couple overlords over a ledge and dropped
them into his base just as he was getting siege tech, so that
didn't kill me. Well, then he flew his buildings around for half
an hour, then he disconnected. Do you see any of his buildings
left on the mini map? I eventually found his last engineering
bay in the top right corner.
