Troubleshooting
If the route does not progress, read the current NPC dialog or quest tracker again, confirm you are in the correct sea and server state, and make sure the target is marked Released. A patch may change costs, cooldowns, or item quantities before community guides are updated.
Do not repeat a rare-item turn-in until the game confirms credit. Rejoin a current server if an update has just shipped, then compare the game label with the official Roblox page or Trello.
