Hey peeps. Im not sure yet, but I realized that I used my Enchanter as follower for a long time. A couple of days ago, I swapped to my Templar. Can any of you confirm if you all use your templar in single player games when doing rifts, and if so. Hire a different follower or no follower at all and just teleport in & out until you get stuck or when it doesn't happen anymore. Since I don't have the problem in party games, I seriously think the Templar follower is causing this (at least for me). Not entirely sure yet, still trying some stuff out.
Swapped from my Templar back to Enchantress and havent had a single loading screen Freeze yet.
And ran at least 9 or 10 rifts since.
