I was just playing casually, I created a nether portal that ended up creating another portal in the overworld. and that ruined all map rendering and portal synchronization

Here is the link recorded today to demonstrate the bug: https://www.youtube.com/watch?v=OuwqgeY5tj8

This bug is making it impossible to continue the game in the surviving world.
I hope you can be correcting as soon as possible, as this is ending the game for many players.
