Describe the bug

I was testing mods for a potential 1.20.1 Modpack, and wanted both a Wither Storm Mod and a performance enhancing mod running at the same time, so I used Canary (version: 0.2.10). But whenever I played with both Wither Storm and Canary installed, it took about half a second for mob's movements to register, and blocks would reappear after breaking them.

Steps to Reproduce

1. Install Wither Storm Mod and Canary 0.2.10
2. Play Minecraft
3. Observe mobs and/or try breaking a block that takes a while to break (like stone or sandstone)

This is a known incompatibility in the wiki.

Turn off Inject Custom AI Behavior in the config for the time being until this incompatibility gets resolved, or remove Canary.

Canary used to automatically detect CWSM and apply the fix outlined here but I guess it's not working anymore. What you need to do is add mixin.ai.nearby_entity_tracking=false to the canary.properties file in your config folder and reload the world, which should fix the lag.

As a side note, disabling "Inject Custom AI Behavior" is not necessarily a great idea since you get rid of all the mob fleeing mechanics and their ability to attack the Wither Storm back. Up to you if you'd like to disable however.
