After completing the battle against the new type of Piglin Base (the one after you get to use Creepers/Zombies/Skeletons for the first time) the game becomes unplayable. 

Occasionally chunks fail to load once you respawn at the Well Of Life (I think that is what it is called?).

Every time so far, the player is immediately teleported back to the top of the well, whenever they attempt to move away. 

When you decide to leave the game and attempt to reload, the saving process gets stuck and so I force closed the program, it always resumes where the video provided picks off. 

This happened on my first and second time trying to progress, this time I recorded it so I could share here.
