Mod NaNny

NaNny, Fixing Health and Absorption Errors

NaNny is a utility mod for Forge and NeoForge that protects a Minecraft server from broken entity values caused by other mods. When an entity’s health or absorption becomes NaN, meaning “Not a Number”, NaNny detects the affected attack, damage, healing, or hurt event and can cancel it before the error spreads.

The mod can also restore an entity to a chosen percentage of its maximum health and record detected incidents in the server log. These configurable safeguards make heavily modded gameplay more stable, and our BoxToPlay servers can benefit from a cleaner, more reliable combat experience.
