Portals in my realm are not linking correctly. I am also getting stuck inside portals and getting killed during the "building terrain" message. I am able to reload a backup to revert to before dying from this, but various portals in the realm aren't linking with their corresponding nether portal.

I am getting sent many 4/4 maps away to random other places, sometimes spawning without a portal, and sometimes it creates a "half" portal. I've attached a photo to show.

This issue is also happening to other users in the realm.
