Germano Mosconi

Hello, before i start telling you my story, i have to make a premise: i'm italian and i used google translate for some words i did not know, so sorry for some grammar errors.

I was playing my Minecraft Vanilla world, as i always do, when i thinked "Let's see if some of my favourite youtubers made a video". I watched some videos, but suddenly i heard a noise. It was like a woman saying something in chinese. I returned in my minecraft world, and i saw something written in the chat:

神狗

Suddenly, my minecraft crashed, before i took a screenshot.

I opened the minecraft launcher again, and my world's name changed. now it's name is "Germano Mosconi". I took a screen of this:

For who is on PC it will appear here >

Do you have advice or can you explain me this? Thank you
