A free mod for Kingdom Come: Deliverance, by Alienhand.
Alternate food spoil is a simple way to make your game less frustrating. This mod for Kingdom Come: Deliverance will make food spoil slower or not at all. This is a great tool to have if you feel the preservation potion does not slow down spoilage enough. However, this will not reset food items in your inventory that are already spoiled. With this, you no longer have to worry about meat spoiling quickly while you are on a hunting trip.
This is an extremely simple mod that does not require any additional files. Simply download the file, create a Mods folder in the game's root path, and extract the zip file into the Data folder.
