Please submit an in-game petition if you have not already. You can open the petition interface using the /petition command in your chat window. That will allow a Game Master to assist you with this directly in-game.
I’d also recommend using the “Repair Broken Data” function on the game launcher the next time you restart, since this often resolves similar issues with being unable to load or interact with certain locations. Please be aware that the repair function will take some time to complete, though.
