Just an hour or two invested today. We got through most of normal difficulty with our druids. Now we’re at act V and we have just killed Shenk. I also managed to find the problem with my network connection. For the past few days, every time one of us would leave the game, the other computer would drop him, which would result in the character not saving. It seems a problem was not with the network, but with my shared stash (I use Plugy). One of the items in the stash corrupted the entire file and that was what caused the drops. I gave a few of my better items to my friend and deleted the stash file. Now everything works perfect again.
