Ugh

[Vash]

What the hell is wrong with b.net? Is it split into mini servers or something?

I can't join any of the games my friends join because they don't seem to exist. Likewise they can't join mine. Sigh

Edit: Some more info...

We can join passworded games fine (whether created by one of us or by another friend).

We've experimented with creating games with characters that have reached various difficulty levels to no avail.

You have been "tagged". This is a mechanism Battle.net use to stop cheaters, but unfortunately it can happen to legit players as well if you drop from the game in an unexpected way. This usually resolves itself after a few days.
