I consistently get disconnected at the same portion of Zero Hour on PC. It's at the hallway after the room with a single heavy shank and a bunch of dregs/vandals on Normal, and after you drop down the first elevator (by where the very first mission in D2 begins) on Heroic. I'm removed from my fireteam and sent back to orbit; I've only tested this with other players in my fireteam. When removed, even if I'm apparently hosting (based on loading in far before my teammates), my teammates can proceed just fine. For a short period before it happens on Normal, enemies will stop responding and respawn when killed for everyone on my fireteam. On Heroic, I just immediately drop out around the spot where you pick up the keycard. There are pretty much no reports of anything like this happening, and it only started happening after the 2.2.2.2 hotfix. I have port forwarding set up (after similar NPC behavior leading to DCs during the D2 beta and vanilla D2), have a dynamic IP assigned from my ISP, and have no other consistent network issues with the game. Any ideas?
