Greetings, Ser_Destroyer!
Thank you for posting your concerns about being stuck underground. Since this matter seems to be more of a technical issue, I have made sure to move your thread from "In-Game Bugs" to "Technical Support." Also, if your character is still trapped underground, I highly recommend contacting an in-game GM by using the /helpdesk command, and they will try their best to get you out from under there. Thanks again for your participation, and I hope everything works out well for you soon!
