My world has three portals 1 at the original spawn the 2nd near the end portal and the 3rd at my new home. Recently i had updated Minecraft to 1.17.0.50 , when I went through my 3rd portal to the nether it spawned me thousands of blocks away from my corresponding 3rd nether portal. Each of my portals would not spawn me in the correct area of where my original portals would be in the nether. It would spawn me in a new area with a new portal the issue has been going for about three days now and the same thing keeps happening.
