I was able to get it to glitch me through the wall. I was using a resource pack. I have put 2 pictures of the resource pack and the seed of the world. I've trimmed the video but it says file is too big still. Can you help me with getting you the video?
All 9 of my worlds are fixed.
All 8 of my worlds spawn me at 0,0 and I have lost all inventory and my enderchests are empty. My world of 10 years everything is gone.
