I'd like to report a bug (or series of bugs) that occurred that led this glitch to be:
I was playing on one of my worlds, and apparently it was updating to the beta (of which I cancelled). It was updating as I was leaving the nether, and then it got stuck in the loading screen. I could hear everything in my base, portal noises, cats, pistons, everything. But never would the screen leave unless I quit minecraft and loaded it back again. I'd like to report that this occurred by doing the following. Keep in mind that this glitch begins when you leave the nether, and persists as such after the update, of which was at the time automatic:

Events before glitch
-Have a series of chests with shulker boxes loaded in the nether.
-Have multiple nether portals in the overworld linked to one in the nether.
-Have a lot of furry friends (cats) (18) (Overworld)
-Exit nether whilst game is updating from 1.10 to beta 1.11.0.7
-Have a number of minecart hoppers in overworld (20)
-Have a genuine Xbox One product (not any name brand extensions like X or 4K or S)
-Game is on hard difficulty
-Banners with at least four decorations are in render in each dimension (15)
-Have a number of chests rendering in the nether (224 chest blocks total, but rendered as 112 double chests)

This is game breaking, and makes old and dedicated worlds harder than ever to play, especially if you have a storage place in the nether, with one chestful of enchanted bows, all in legitimate vanilla survival
