On PS4 version (i think it is bedrock) after the second last update, I tried using my saved nether portal that goes to my already made house in the nether. Now it will randomly send me thousands of blocks away sometimes with a nether portal behind me, sometimes not. This is super stressful because I can’t go into the nether now out of worries that I might be placed somewhere super far, and it works that way if I am leaving the nether as well. Would love to be fixed in the next update!!
