I'm also on PS4, not having any PSN issues.

As I've stated... I've made it into the game twice now... but then quickly disconnected again.

I had joined a party in the PF before all this started happening, a player was looking for help doing coil t1-13 unsync... I wanted the bonuses for WT, so I joined up. We completed t1, then everything went crayzah right before we took on t2 final boss.

I mention that because each time I got back in the game, I was still in the same party. So the other 7 random ppl that joined in PF are apparently all having the same issue as far as I can tell...
