Can't load chunks fast enough to justify using an elytra to travel. Tried to go through the backbreaking process of creating tunnels and travel systems in the nether instead. However; depending on how many chunks have to load, and if there's any other portals within roughly 200 blocks, the game tries to link them. This causes several errors of trying to transfer between dimensions. My only way around the problem thus far is exiting the game during the transfer, going back to the other portal it's linked to on the opposite side, using it again; and then rebuilding a new portal manually in the Nether. Something related to the script of automatically generating portal frames isn't working; and this has been a consistent issue that others have reported.
