Twice today while playing H4 BTB on the map Forge Island, I was disconnected from the game (sent back to the loading screen where I could still hear my teammates talking), and received a ban - both times, within a span of 2 hours. This seems to be a regular occurrence on the Forge Island map (as well as on Impact). Most of the time I don't get disconnected but watch almost everyone else on my team and the opposing team get kicked out until there's like 2-5 players left out of 16.
Is this a known problem with the two maps? Since we can't choose the maps, I'm at the mercy of the game composer and now I'm cruising for a 3rd ban today, by no fault of my own, if this happens again! And I like the Forge Island map which makes this extra crappy.
(Also, I actually did quit a game today after all but 2 or 3 of my teammates did - but that didn't result in a ban.)
