Description

This mod fixes an old bug in Minecraft that causes the "Max Health" attribute to be ignored when a player joins the game. This bug will cause players with a health value greater than the default limit of 20 to be reset back down to 20 when they join the game. For example if the player is wearing a helmet that gives them +10 max health and they leave the game while having 25 health their health will be reset back to 20 when they rejoin the game.

This mod can be installed on the client and server. When installed on the client the bug will be fixed for your singleplayer worlds. When installed on the server the bug will be fixed for all players playing on the server, even those without the mod installed on their client.

 

You can test this bug using the following steps.

1. Create a new world with cheats enabled and creative mode turned off.
2. Use the /give command to give yourself a helmet with +10 max health. /give @p diamond_helmet{AttributeModifiers:[{AttributeName:"generic.max_health",Amount:20.0,Slot:head,Name:"generic.max_health",UUID:[I;-12158,12468,122112,-24936]}]} 1
3. Equip the helmet. Your max health should go from 20 to 30 (15 hearts).
4. Heal the player causing their health to be over 20.
5. Save the game and exit.
6. Rejoin the game.
7. Your health will be reset to 20. If the mod is installed it will not be.
