i actually dont know how to link save files, and searching online really isnt leading me anywhere, im sorry.
i was however able to replicate the problem and discover a different problem in sandbox mode with only Ammo Loader+ and AAI Industry turned on.
by building a single burner miner on a coal patch and having it dump into a loader, it should just keep powering itself after its primed with one coal, however nothing happens, the loader never links to the drill and never provides coal to the drill or any other drill i put down.
on the other hand, i did the same for turrets just to double check and found a different problem, if i put ammo into the loader it does give the turret ammo, but now if i put piercing ammo into the loader it does not UPGRADE the ammo in the turret, it just stays there, same for if i load the loader with uranium ammo. its very strange.
those are my definitive findings doing tests with ONLY Ammo Loader+ and AAI Industry turned on. none of the other mods i play with have caused any problems with Ammo Loader+. im sorry if im not able to be more helpful.
