Describe the bug
When booting the game, and joining a world, after around 4 seconds and loading chunks, the game slowly goes to a halt after around 5 seconds of decreases in frame rate, peaking in a halt. The game does not crash and must be closed via kill.

To Reproduce
Steps to reproduce the behavior:

1. Boot the game and immediately enter a single player world
2. Experience the game freezing.

Expected behavior

The game runs as expected and does not experience a freeze after brief gameplay.

Checklist

• I am using the official version of the mod.
• I tried the latest development version but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Additional context
Based on the log and nature of the freeze, I assume this comes from an infinite loop where entity tracking is not escaped, though my analysis may be incorrect.

Here is the specific thread dump I am referring to:

Try reproduce with just vmp on a fresh world.

Error doesn't happen on a fresh instance on same version, realistically a mod incompatibility. Would you like me to test which specific mod has an incompatibility? (if any)
