Same, pally hit 80 and I was flying through the coreway and fell through the world and now stuck in disconnecting loop. Tried Blizz “Character stuck” feature, didnt work. Tried the “suggested” thing of waiting 15 minutes, I waited 30 minutes, still nothing… would love to log back into my pally but I cant and I’m sure blizz isnt going to answer or fix it anytime soon…
