Description
Reanimal patched — server-side hotfix for packet/data corruption
What this project does
This is a minimal, server-safe patch for the latest versions of Reanimal. It fixes a critical bug that can corrupt networking data by preventing invalid (null) pathfinding debug information from being serialized and sent to clients.
The bug being patched
In current Reanimal builds, pathfinding debugging can generate null/invalid debug data. When that debug payload is packaged into network packets, it can produce malformed packets (and in some cases corrupted synced state), leading to issues such as:
- Client disconnects or desync
- Spammy network errors in logs
- Unstable behavior during mob AI/pathfinding activity (especially on busy servers)
How this patch fixes it
This patch disables pathfinding debugging output so the faulty debug payload is never created or transmitted. No gameplay systems are removed—only the debug pathway that is causing the corruption.
How this affects players / server owners
- Servers become stable under normal gameplay (even with lots of mobs/pathfinding).
- Players won’t randomly desync/disconnect due to broken pathfinding debug packets.
- No gameplay balance changes. AI behavior remains the same; only debug visualization/data is suppressed.
- Tradeoff: you won’t have Reanimal pathfinding debug output enabled while using this patch.
Who should use this
- Anyone running a multiplayer server with Reanimal who wants to prevent network instability/corruption.
- Singleplayer users generally won’t notice a difference unless they rely on pathfinding debug features.
Notes
- This is intended as a temporary hotfix until the upstream mod resolves the underlying issue.
- The patch is server-side focused and designed to be safe to include in modpacks that run Reanimal.
