An autosaver that wouldn't suck would also need to save any minigames running, any other ScriptObjects existing, any current schedules, etc, etc, etc, and then interrupt the appropriate stuff when loading (but let new stuff run fine).
I was referring to brick auto-savers that wouldn't have to redundantly save every brick in the server periodically. I still have no clue how V21 minigame stuff works, but I assume that starts up with the server.
Slayer and CityRP/G start properly on their own.
It's not really necessary to save absolutely everything because most mods should have start-from-termination mechanisms.
The autosaver I plan to make will save bricks in chunks (and only update a certain chunk when a change is made) and will load the bricks when the server starts.
