Features
Save without freezing
Option on the Manual world save page (off by default). Automatic world saves (server/host) spread the copy the game makes before writing over several frames (the time used per frame is decided automatically: more on a dedicated server, less on a player's game, less again when the frame is already heavy; nothing to configure); everything that changes during the copy is copied again in the last frame, so the save is one consistent picture (no duplicated or lost items). The game's own file writer, backups and chunk files are kept. For every player with the mod, automatic character saves build the explored-map data on a worker thread. Logout, exit and immediate saves always use the game's own save.
Ground item cleanup
- Optimization – removes items that stayed on the ground too long, to keep the world light and keep frames high. Off by default. Time on the ground (default 6 h, 0.1–720) counts server running time; an item a player picks up and drops again starts a new timer. Items are removed bases included when their area loads and while it stays loaded (a few per frame, never all at once). Clean when the server starts (default on, only with the cleanup on) removes old items right after the server starts, so the world loads clean. The button Clean the world now (admins, two clicks) scans the whole world in small slices – one chunk per frame and a limited number of removals per frame, even in areas nobody has loaded – and removes every item older than the limit. It never touches items inside chests, carts, boats or inventories, placed pieces or fish, and items whose age is unknown are kept. Nothing is logged.
⚠️ Experimental
This mod is still experimental and may contain bugs. Back up your world and your character, and turn features on a few at a time.
