Neiter the server nor the client crashed. In singleplayer it works fine.

 

Here's the problem code:

@SubscribeEvent
public void playerDied(LivingDeathEvent e) {
	if(TobyModXP.keepXp) {

		if(e.entity instanceof EntityPlayer){
			total = Minecraft.getMinecraft().thePlayer.experienceTotal;   [b]<- Line 29[/b]
			lvl = Minecraft.getMinecraft().thePlayer.experienceLevel;
			bar = Minecraft.getMinecraft().thePlayer.experience;	
		}
	}
}

 

Thx for helping

Minecraft.class is client-side class. Dedicated server doesn't have it.

Aside from the fact that you cannot use client-side classes in common code, you are also doing everything wrong.

 

You should be doing it rather this way:

@SubscribeEvent
public void playerDied(LivingDeathEvent e) {
	if(TobyModXP.keepXp) {

		if(e.entity instanceof EntityPlayer){
EntityPlayer p = (EntityPlayer) e.entity;
			total = p.experienceTotal;   [b]<- Line 29[/b]
			lvl = p.experienceLevel;
			bar = p.experience;	
		}
	}
}
