I made hot cocoa in the kettle and it won’t allow me to take it out now. The kettle just keeps whistling and it’s very obnoxious. Any ideas on how to fix this?

Sorry, the Kettle belongs to the Farmer's Respite add-on; it's not an FD workstation.
If I recall correctly, you need to put a Glass Bottle in the container slot to take it out, or right-click the kettle with it. Good luck!
