WukongMP SDK 0.3.1 is live - memory and CPU fixes, Bullguard cutscene, reconnect fixes

Build: WukongMP SDK 0.3.1, 17 August 2026 Rollout: live now. Binaries and Docker images are up, and our hosted servers are already on 0.3.1. Action needed: update your server, and recompile your mods. There is one breaking change.

What this release is mostly about

Resources. The server no longer grows its memory footprint the way it did in 0.3.0, and CPU usage on Linux hosts is down. Those were the two most reported problems with 0.3.0, so they went first.

Fixed

  • Server memory footprint no longer grows the way it did in 0.3.0
  • Excessive CPU usage on Linux hosts
  • The Bullguard fight cutscene failing to trigger, which soft-locked progression
  • A range of bugs that showed up when a player reconnected during a game

Known issues

Three gameplay problems are still open, and all three can affect a normal campaign run:

  • Enemies can disappear when players move far apart
  • Hidden plant enemies can malfunction after a reconnect and fight in their plant form instead of hidden
  • Bosses can die instantly for some players while others in the same session get a normal fight

Every one of these came out of community reports. That is genuinely how we found them, because they reproduce rarely enough that our own playthroughs missed them. We are investigating all three and will fix them in upcoming releases. If you hit one, a clip and a rough idea of what happened just before is the most useful thing you can send us.

Breaking changes

String fields in three core components now use NativeString256 instead of standard strings:

  • NicknameComponent.Nickname
  • PlayerComponent.Nickname
  • TamerComponent.Guid and UnitPath

Mods need recompiling, and in most cases a .ToString() where you previously read those fields as strings directly. It is a small change to make, just not one you can skip.

Availability

Binary packages and Docker images are both out. The Docker image is ghcr.io/readycodeio/wukongmp-server:0.3.1, with the run command and a compose example in the Quick Start guide. Installation and quick-start docs are updated for 0.3.1.

Reporting problems with this build

Client crashes, desync and broken gameplay go in WukongMP Discussion. Server problems in WukongMP Server Development. SDK and scripting questions in ReadyM SDK. Put WukongMP SDK 0.3.1 in the title, for example [BUG] WukongMP SDK 0.3.1 - boss dies instantly for one player in a 3 player session.
