Occasionally in modded Minecraft, the health of a living animal, mob or player will have their health glitch out and become a non-finite number.

The symptom of this is invincible mobs and players with zero hearts.

This server side mod attempts to spot these errors as they happen and prevent them.

It also tries to log any relevant error information for debugging purposes.

It can be configured to announce errors to players and/or try to automatically fix the problem.

It can also be configured to run on multiple event buses, which makes diagnosing the problem easier.

It adds a console command to fix broken online players, if the automatic fixing isn’t working or if you just want the mod as a repair tool.

It tries to be compatible with FirstAid, PotionCore, and ScalingHealth.
