If your character gets stuck in a position you cannot escape from, you can type "/unstuck" without the quotes into chat to be moved a short distance away. This command is only intended to be used if you find yourself unable to navigate on your own, like falling between rocks you cannot climb out from. It is not for escaping an enemy base or avoiding a fight. Once you use "/unstuck" you will have to wait a period of time before it becomes available again.
