AC story mode
I lagged out of the game and couldn’t enter the instance. I left party and rejoined, left party and relogged and then rejoined and still couldn’t get into the same instance with my party members. So we just restarted the instance .Party member had to leave so someone left to find another and he and the new party member wasn’t able to get into the same instance as us. Party members and I used both the message pop up and tried to enter the instance with the portal.
I hope this gets fixed soon.
