Description
# Slay the Spire 2 — LAN Multiplayer
The base line fork this fix is here
This mod enables you to play Slay the Spire 2 with friends over your local network without needing to use Steam.
## Additions
- Also with this mod I patched the annoying "Disconnected: State Divergence" message away.
## Installation
1. Extract the zip
2. Drop the `SlayTheSpire2.LAN.Multiplayer` folder into your `mods/` directory
3. Launch the game, make sure the mod is enabled in settings.
4. (optional) if there nonetheless should appear any errors for example because of another update grab the log and post it here
## Usage
Host starts a LAN game from the multiplayer menu, clients join using the host's local IP address. That's it.
## Changelog
**v1.6.4**
- Fixed a Harmony `AmbiguousMatchException` crash on mod load caused by a new `SaveRun` overload added in game v0.107.1 — patch now targets the exact method signature instead of matching ambiguously
**v1.6.3**
- Fixed a startup crash (`ReflectionTypeLoadException`) caused by game v0.107.1 adding a `ShouldBuffer` property to `INetMessage` — all custom network messages now implement it
- Added missing `IPacketSerializable` implementation to player name request/response messages for consistency with other message types
- Fixed the client-side resync request flag getting permanently stuck if the host never replies (e.g. disconnects mid-resync) — added an 8-second timeout so the client can retry
- Fixed a potential `NullReferenceException` in lobby cleanup when the net service property couldn't be resolved
## Compatibility
Requires game version v0.107.1 or later.
