For those having issues with the F9 menu try creating a new game. If you had a previous save data it may not be compatible. What I suggest is make a copy of your saved data. Download the 0.81 version of the game. Enter the game with the same screen resolution you are using. Pick "New Game". Once that is loaded, press "Right Control + C" to enable Advanced Cheat. Then try using "Right Control + F9". It should work at this point. Cheat the items needed for the fireplace and the tent. Once you made the tent, press Escape and click Save. Leave the game go to the folder R-Life v0.8.1 Public Build 32-bit\R-Life_Data\SaveData then overwrite your previous save data on to it. Hopefully this helps!
