**Updated Mod Rules:**

1.16.1:

• [WorldPreview v4.0.2](https://github.com/Minecraft-Java-Edition-Speedrunning/mcsr-worldpreview-1.16.1/releases/tag/v4.0.2) 1.16.1 is allowed.


World Preview for 1.16.1 has been updated to v4.0.2. This fixes the IllegalStateException invalid lock crash by combining the fix New Horizons with an additional safety net. (The previous update, v4.0.1, was an unsuccessful attempt to fix the crash.)
