Ubuntu user here - I have the same bug - I cannot cook anything with meat. Cooking mushrooms is not a problem. Also firepit for clay is working. I tried also
- removing the fireplace and placing a new one,
- creating (baking) a new pot.
- cooling the firepit to 0^C a and restarting with different "fuel"
- quiting to main menu and going back into the world
Those things did not work so I think it's a bug with meat recipes.
Edit1: But cooking meat directly over firepit is possible (not in the pot).
Edit2: after cooking some poultry it went back to normal - no idea why it worked
maybe it's a workaround for this bug? @MrPole - please check
