@Petar, I broke my nether portal and rebuilt it (pretty much first thing I did as I didn’t like the location). This still happens for me.

@Scott, that seems reasonable. I wonder if the calculation is running in a different thread, but the main code isn’t waiting for it to complete?

PS4, and I’ve had this three times over the last week.

First time was going from the Overworld to the Nether; no portal spawned on the Nether side, and it was a long walk/mine back.

Second time was also going from the Overworld to the Nether. Weirdly this time a portal spawned, but I didn’t dare use it. Conveniently of course I’d already mined out a route back to my base!

Last time was from Nether to Overworld. I got lucky though, because those coordinates happened to be about 50 blocks from my original spawn point in the world, so it was just a short walk (once I’d managed to get down from the tree) to get to my original base where I had a donkey tied up. Of course if this happens again I’ll have to walk all the way home.
