The same glitch when eating while going through the nether portal will teleport I to the same overworld coordinates in the nether (ex. Your in the overworld at 123 56 650 itll take you to 123 56 650 in the nether,) then while teleporting u back itll do the proper 8x coordinates basically teleporting you thousands to millions of blocks away from where u started with no way back. When u go to nether when this glitch happens the portal wont appear either its invisible and will suffocate you. But if u update a block some of the portal will appear and works like all others just fine) (it's not a rare glitch either it happened twice within 10 time of going
