My husband and I play together on couch co-op and our infernal hordes constantly glitch and won’t let us progress to the next wave or the boss and we just have to bail, GA chest doesn’t give ANY GA gear, only one person’s aether count shows up in the corner, minions disappear and can’t be resummoned so have to teleport out and back in to get them back. And when my husband plays pits either with me or by himself he doesn’t get ANY obducite from it at all.
I’m sure there’s one’s I’m forgetting, this is probably the buggiest season we’ve ever played and we’ve been couch co-oping diablo since D3
