It was getting dark so I decide to sleep. My bed is situated against the nether portal. After the end of the animation, I spawn back on my feet but I've been tp into the Nether at the exact same coordinates than in the OverWorld with a new portal generated behind me. I decide to took it but it worked normally so I was around 50 000 blocks away "yea". After about 30 min of me walking because I don't want to lose a full set of fully enchant netherite armor and tools I dropped out and suicide me. Thanks the bug. I'll keep my bed away from you, you damn nether portal.

Unfortunatly I didn't thought of cliping the bug sry

Edit : I forgot to say that I alt+tab during the night animation. I know the game really don't like it but yea.
