if you’re at somewhere else and not at your base then you should go out and clear the thing. Go back in and don’t enter it, just go to somewhere else and then go back you should be fine. For the one at the base there are two way which, if you have the spikes on your base then you should go up to it then try to kill you self. If you don’t have the spikes then you gotta wait until the hunger goes down which I don’t think it works anymore but you can try to go out and clear the thing again then go somewhere else or delete the game. Make sure you save it first and the install it again, open the app then try to go to somewhere else and then go back to your base. Don’t enter you base after you open the app again, just go somewhere and then go back.
I hope that help :)
