History
no save loadedDrop a .sav here
Parsed entirely in this browser tab; nothing is uploaded anywhere. Saves live in %LOCALAPPDATA%\FactoryGame\Saved\SaveGames\ — drop the three autosaves together and the history fills in. Your game’s Docs/en-US.json can be dropped here too.
The game keeps three rotating autosave slots, so what happened an hour ago is already gone. Load a save and every one after it is kept here — leave the tab open while you play and the session draws itself.
