This mod requires the following mods to function
denikson-BepInExPack_Valheim
BepInEx pack for Valheim. Preconfigured with the correct entry point for mods and preferred defaults for the community.
Preferred version: 5.4.2351README
Rusty Heathens ServerSync 1.0.0
Conservative server diagnostics and guarded bounded network scheduling for Heathens' Haven.
ServerSync does not replace Valheim networking. It instruments the existing send cycle and, when explicitly enabled on a compatible dedicated server, can allow a tightly bounded additional pass through the same native scheduler.
Current compatibility
- Valheim 1.0.16 and 1.0.17 only.
- Network version 40.
- BepInExPack Valheim 5.4.2351.
Unknown game/network versions fail closed. The bounded scheduler also stays disabled if the reviewed network method fingerprints do not match.
Modes
Observe is the safe default for new configs. It records compact diagnostics and adds no network-send work.
BoundedScheduler is an experimental dedicated-server option. It may invoke Valheim's existing round-robin send method one additional time in an update when the configured frame, budget, save-cooldown, compatibility, and overlap guards allow it.
Existing configs are preserved when upgrading.
What it does not change
ServerSync does not alter packet formats, send-queue limits, ZDO ownership, inventories, chest contents, world data, or save formats. It also does not enforce the approved-mod allowlist; that remains a separate ModGuard responsibility.
Installation
Install the same ServerSync version in the shared profile and on the dedicated server. The scheduler activates only on a compatible dedicated server; clients remain observation-only.
For manual installation, place RustyHeathensServerSync.dll under a BepInEx plugin folder and restart Valheim/server.
Diagnostics
When reporting an issue, include the relevant [RHSS] lines from BepInEx/LogOutput.log, the Valheim version, BepInExPack version, ServerSync version, and configured mode.
CHANGELOG
Changelog
1.0.0 - 2026-10-07
- Add reviewed Valheim 1.0.17 / network version 40 compatibility while preserving 1.0.16/40 support.
- Replace the old single-version gate with a narrow game+network compatibility gate.
- Preserve runtime method-fingerprint guards for
ZDOMan.SendZDOToPeers2andZDOMan.SendZDOs; bounded scheduling disables itself if reviewed methods differ. - Keep future game/network versions fail-closed instead of forcing native hooks.
- Preserve Observe as the safe default for new configs and preserve existing BoundedScheduler configs on upgrade.
- No packet format, queue-limit, ownership, inventory, chest, world, or save-format changes.
0.1.2
- Dedicated-server Steam transport quality probing degrades gracefully when unavailable.
- Harmony patch invocation build fix.
