NaNny (Fix NaN Health / Absorption) Mod 1.16.5–26.1.2
MODNaNny is a critical server stabilization mod that protects Minecraft entities from becoming corrupted when poorly coded mods calculate floating-point health or absorption as Not a Number (NaN). Unhandled NaN health values often result in unkillable immortal mobs and broken damage events.
NaNny is a critical server stabilization mod that protects Minecraft entities from becoming corrupted when poorly coded mods calculate floating-point health or absorption as Not a Number (NaN). Unhandled NaN health values often result in unkillable immortal mobs and broken damage events.
The mod hooks into living damage, hurt, and healing events to intercept invalid floating-point values, automatically resetting the entity's health to a configurable percentage of its maximum. It prevents server console spam and keeps combat mechanics stable.
