Times Vengeance

This never used to be a problem for me until the 1.16 update. Now, after every two or three sessions it defaults to Steve or Alex, even if I wait on the main screen for it to load.

I'm going to give my own testimony on this, as it affects the Xbox One Edition as well. Outside of spawners, Nether mobs are practically non-existent after you go through a Fortress once. Also, the amount of hours I've spent over the last several days searching for wolves and ocelots (just for a couple simple achievements) has been ridiculous. I finally found the five wolves, but have not seen a single ocelot. I'm seriously wondering if they even exist (I know they don't spawn on peaceful). This terrible spawn rate of mobs is making some aspects of the game impossible.

This affects the Bedrock Edition on Xbox One as well. I'm trying to farm Wither Skeletons and Ghasts, and it's impossible due to nothing respawning.

So, any progress on this yet? I haven't made any new copies of my world, so I haven't had this glitch happen since I last updated this, but since the disable autosave option was taken away, copies are my only way to test things and help people with achievements. I don't want to do this in fear that it'll break my world.
