Teleportation lol

I was about to go looking for the netherite upgrade template in my neather from my base which is at the coordinates 2616 -700. As soon I went into my portal my game froze on the loading screen and I restarted it, when I logged back in I was at the coordinates 2616 -700 but in the neather!!! It took a long time but I made it back home but other may not so pls fix this
