I don't know if this has been reported here and closed as fixed before but on Hel Ra Citadel.
1. If team wipes, the bottom and top bosses will disappear.
2. The Gargoyles that spawn on bottom part when entering the first and second gate will run into and get stuck in the walls leading to team often moving forward and while clearing the adds and boss the Gargoyle pounce sometimes hits the bottom party.
3. if a party member drops or by accident selects to respawn at wayshrine they might not be able to go through certain doors and reach the group.
