That's probably because the testers are using newer hardware, and have low latency due to being in California near the servers. Also, if they are running on a test server, they won't have the massive amounts of lag that us normal players deal with daily.
Here's the thing - all their testers say they're unable to replicate the lag bug. Even though EVERYONE FREAKING TELLS THEM THERE IS ONE.
I have this issue too, quest chain dead-ends for non-KMS classes most likely.i had finish TO PANTHEON and it said i can proceed to SUPPORTING HELISEUM RECLAMATION HQDid you check your lightbulb quests? If not, try going to Tiron (who's in the map leading to the Heliseum HQ map).
but i didn't get any quest from Beldar or any NPC, and my character is beast tarmer
