I played with my friend survival and he was from cracked player on online server and there was a mod to make him be able to connect.

So I also have a datapack that makes players drop their heads on death.

When I placed his head, there was a lagg because his name doesn't exists on mojang services.

A moment ago I placed his head, and it crashed my game client and the mojang services....

I've tried to join servers and I wasn't able to connect to any of the premium servers. INCLUDING HYPIXEL
