If your island has some sort of issue/bug (queue issue, glitched building, survival world) and no admins/devs are online, it can sometimes be a good idea to re-load your island. All you need to do is have everyone leave your island, and wait until the button you click to join your island is an anvil. This has helped me a few times, and I felt it would be a good idea to share it. This will not work for every glitch, but it is a good thing to try before trying to get the attention of staff-members.
