Hi, casual single player here. Game froze in Fautz - error message quickly appeared and disappeared, couldn't see what it said...
From D2stats notifier I saw (when the screen was already frozen) that a Taha rune dropped (alongside with a unique ring and some random yellow amulet); since I never dropped a Taha I'm guessing the crash could have been because of it... ? Don't know if it helps, I'm playing ATMG sin.
