State Ledger

The disk I/O bedrock of the Realistic Farming mod ecosystem. StateLedger is mod 1 in the load order: it collapses every companion mod's savegame data into one atomic XML write and one atomic load. Without it, each mod writes its own file in one save window, and a crash or force-quit mid-window can corrupt the later files and lose progression permanently. StateLedger removes that failure mode by batching everything into a single file.

There are no settings and nothing to configure. Install it, keep it loaded, and let the companion mods use it.
