I've been trying to deal with this issue, but it's been incredibly bad today. I was in Malikah's Well, and I 90002ed 3 times before the first boss (4th time during the first boss). I gave up at that point. Nothing else is disconnecting when this happens (discord, netflix, etc). No lag or hiccups in game before/during this problem, either. Also, it's only been happening since 5.3's release for me. Did all the troubleshooting steps the reps have posted over and over on this forum, and it hasn't helped. Really not sure what else to do at this point, since it seems reps stop posting after they've given the basic troubleshooting steps.
