[1.10.2] Server Crashes with NoSuchMethodError

[WillR27398]

My mod works fine in single player, but when trying to create a server, this method apparently doesn't exist anymore in my entity class:

 

getEntityAttribute(SharedMonsterAttributes.MAX_HEALTH).removeAllModifiers();

 

Ticking entity java.lang.NoSuchMethodError: net.minecraft.entity.ai.attributes.IAttributeInstance.func_142049_d()V
at com.test.entity.EntityCustom.updateStats(EntityCustom.java:805)

Line 805 is the one shown above and line 533 just calls the method that contains it. I don't know what causes this or what I have done wrong.

removeAllModifiers is Client side only. Instead call removeModifier()

Oh, I see the problem. Hopefully I can fix any problems I have now, thanks!
