Does anyone else have problems getting disconnected during the map Upheaval. I lose connection 75% of the time I try to play it. I have no connection problems with any other maps.

There is a problem with that particular map for some people. I get mini lags where I stop then move 10 - 20 feet, that's if I don't get disconnected. It's intermittent, so I tolerate it.

used to happen to me all the time ... no rhyme nor reason

Ya I get it too,I try not to move and I still get d/c ed.My ping shoots up and down alot. I wish I knew  how to fix it.It's the only map that does it for me

for some reason, this map has always been a problem map.  when the game first can out it was virtually unplayable for most.  now its gotten better, but there is just something about it.  also, it is at the end of our server rotation, so that may have something to do with it.
