How do you reload the latest save game in Kingdom Come: Deliverance?

This save system is intentional, to increase the effect of the role-playing element of the game.

Before the 1.3 patch

players only had two ways to save the game: finding a bed or drinking a liquor known as Savior Schnapps. However, patch 1.3 has updated the complicated save system of Kingdom Come: Deliverance by introducing a “Save and Exit” option that can be used at any time.^*

With "used at any time" the writer means you can exit out of the game at any time, and once you reload the game, it will load that saved game. However, this saved game will not be accessible through a menu: it will be loaded again after dying or restarting the game, and it will be overwritten once the feature is used again.

There are several ways to change this feature however, as there is a lot of controverse surrounding it.
Here is a manual approach, and here is a mod.
