So last few days my bnet will randomly drop me from a game im playing, even tho my net is still on and working fine. The odd thing tho is that i dont get dropped from the game after the usual 50 seconds or whatever it is till it drops me, but i can stay on the lil screen saying "Surrender" that comes up when you lag and its really weird, and then when i eventually click surrender i go back into sc2 perfectly normal except the score screen wont load, but it wont say like "reconnected to bnet, achievements restored blah blah".
Anyone had this happen to them before?
