AI Reducer

Server side mod, has some features to reduce the lag from AI in modded environments.

Highly recommended if you're using Lycanites Mobs in your modpack.

You can also slow down rabbits! (In 1.12.2)

Versions are available for Forge 1.12.2 and Forge 1.16.5

Recommended for use in your modpack if:

• Your modpack has a mod that increases the max entity radius (Lycanites Mobs, Advanced Rocketry, Immersive Railroading, etc.)
• Your modpack runs Ice and Fire (1.12.2)
• Your rabbits are too smart (1.12.2)

In the 1.16.5 version, the mod will help you only if your pack has a mod that increases max entity radius (for example, Lycanites Mobs), otherwise it'll make it run slower. Be careful!
