Guild Wars 2

As the title says someone could join the Dungeon (Cathedral of Flames – Path 1) after he
was kicked for being afk. He could even walk from the start to us to the first encounter
so we could re-invite him.

I guess he still had the “Join Dungeon Pop-Up Screen” when we kicked him and
that this could be used to drag 3 extra Players into the Dungeon, or would those be kicked after a while?

I don’t really get your bug or question or so, but here’s the trivia for any instances

• The one who opens the instance is the instance owner.
• If the instance is closed, anyone will be kicked.
• Anyone kicked from or left the party will automatically kicked from the instance.
• If the instance owner is kicked or left the party, the instance will be closed (?)
• Anyone from the party who is on the map gets an invitation for joining the instance upon players relog, waypoint usage or when the instance is initially opened.
• If the instance owner changes character or leaves the area of the instance, the instance will be closed.
• You can not open an instance while another one is still opened by the party.
• If the instance is empty for 5 minutes, it will be closed.

Nretep all of is know to me and the 5th of your list
could be the reason for the bug/exploit.

Here what happened in a more structured way:

- We formed up a Group of 5
- “Leader” opened the Dungeon. All but “Mr.AFK” joined.
- We fought the first Trash-Group (CoF Path 1)
- “Mr.AFK” got kicked from group (he was still outside)
- shortly after that “Mr.AFK” was standing beside us
(he joined the Dungeon after he was kicked or was
already joining the Dungeon while being kicked)
- we could re-invite him and finish the Dungeon

I hope its clear now.

Edit:
To sum it up
-either the Dungeon-Invite-Screen does not disappear when a Player gets kicked from the group (before he enters the dungeon)
-or if a player gets kicked from group while he’s loading/entering the dungeon he still
gets into the dungeon
