These are on Castle of Steel being seen by multiple people in multiple runs, maybe other servers can verify if they are server wide.
Running checklist count incomplete. Does not show gatherable running count so you basically have to keep track in your head. I know it’s only 10 but it’s easy to forget when you are doing so much. If it’s required for gold it should be accessible on the pull down check list you check with named bosses, mobs, team wipes.
Final bosses don’t always show their HP bar which is very important as you have to kill them together at similar HP.
When final boss mage (sry forgot name, the smaller one) does an AOE ability in the center of the room (not pillar activation) he emanates a bright white flickering light. IDK if this is intentional or a visual bug but this is very dangerous for people with seizures and other light sensitivities and should be fixed/removed ASAP.
Thank for your attention to these issues!
