Thank you scraps345. Did you try to recreate the party? As in, completely new.
And is anyone else with VIP experiencing the same issue?
Great! It could be that creating new party after the update is required as changes been made to the memorial dungeon system. If the issue comes up again to let us know.
As for the memorial dungeon error experienced on Chaos server, this was reported to the staff. It has nothing to do with the current update, it is a recurring issue to map zone. It can be fixed... hopefully™.
Yes I change parties quite often because it bugs out so much.
