About this project

BepInEx 5 + Harmony, host-authoritative, over Steam lobbies and P2P with its own reliable layer, plus LAN discovery. The host's save is sent to the client. README lists shared time, weather, quests, crafting, world objects, combat, drops, zones, workers, dungeons, fishing, dialogue and cutscenes, and DLC support; each player keeps their own inventory. Latest release 1.2.0 Beta (2026-09-04). A 9-test two-client suite (join, shared intro cutscene, movement, sleep, eating from a quick slot, ping) passes on 432b1d0 plus three fixes sent upstream as pull requests; without them a client can't use food from its own inventory (issue 22). MIT. Write-up in games/graveyard-keeper.

About this project

BepInEx 5 + Harmony over a friends-only Steam lobby and P2P, with its own reliability layer. README lists movement, time, chopping, foraging, garden beds, graves, corpse carrying, building, crafting, shared chests and weather; the second player has a personal save and their own quest journal over the host's world, and NPC villagers and dungeon mobs are not synced yet. Latest build v0.1.5-test2 (2026-08-30, pre-release). Players report a client desync with NullReferenceException spam, a host soft lock and large-item duplication. The repo ships Steamworks.NET.dll and a 14 KB Stitch.dll in Multiplayer/lib. The author also wrote the reliable transport in Back From The Grave. MIT.
