I built a new nether portal in one of my worlds. I went through the nether portal and it crashed (as usual). I tried to go in the world about 3 times before it finally loaded. When I got in the world, all of my stuff was there but the nether portal was not. I had to kill myself. I destroyed the old portal and rebuilt it in another spot and went to the nether again. The nether portal was not there and I was forced to kill myself again. Please fix this.
