I was in my Minecraft survival world, I built a portal to the nether and a few days later I built another one, inside the nether I broke the first portal I had built and built it again, when I went to the overworld I returned to my portal and approached to enter , but when I did it it just got stuck on generating terrain, and I waited a few minutes and it kept generating the terrain, when I left and went back in it appeared in my house, and when I returned to the portal the same thing happened, it got stuck on generating terrain, and Then I went out and came back in but it only appeared in a random part of the nether, I killed myself in minecraft and it appeared in my house. Then I entered the portal but this time it finished loading and it appeared in the normal place where it always appeared in the nether, but when I tried again to see if it was really solved, it got stuck again in generating terrain.
