I’m create this topic to show people a method to not get stuck in party quest events.
The simple method is to not share the same camera (field of view) when a event scene occurs. So, above a list of things to do.
-
You and your friends need to stay away from each other when delivering quests, since this events can occur after the delivering.
-
One of your friends always go in front of others when going to a place of a quests. If the place is a boss the others will be teleported anyway.
I tested this method this afternoon with my friend and we did the quests normally doing this steps ( except the times we forgot to follow the rules 
)
