NRaas Saver is basically an annoying but effective alarm clock to remind players to save at regular intervals.
We are not adding an auto-save mod because it is not possible to play the game while it is being saved and no way to stop the game from saving once such a procedure has begun. For players where saves take seconds of course that wouldn't likely bother them much, but for those whose saves take several minutes that would probably drive them crazy.
Others may have to correct me on this, but I think AwesomeMod (a Core Mod) does offer an auto-save feature?
