The second after you're done installing Kingdom Come: Deliverance, grabbing this mod should be the very first thing you do before even loading up the game.
Having to rely on limited quantity Saviour Schnapps to save your game is an amazingly bad design if I've ever seen one. While it may add a certain amount of challenge to Kingdom Come: Deliverance, it also tends to destroy any desire to keep playing the game.
The saving fiasco becomes less of a problem after you gain the ability to reliably brew your own Schnapps later in the game, but in the early stages of KC:D, it makes re-loading an incredibly frustrating experience, as autosaves are few and far between.
Get rid of the frustration entirely by downloading the Unlimited Saving mod to unlock unlimited saves across the game, whether you've got any Schnapps on hand or not!
