Simple tool to prevent Steam from Updating Beat Saber whenever there happens to be an update so you dont need to copy around files and end up possibly wrecking your setup.
2. Download the latest version of the application from the releases
3. Rest should be pretty much self explanatory. Whenever Steam wants you to update Beat Saber you can make use of this to prevent it from actually updating.
Since Steam thinks you are on the latest version, eventho you are not, obviously your files differ from the ones that should exist for this version, so to actually do the update once mods are ready simply to go the properties of Beat Saber in Steam and verify the integrity of the game files.
