My world did something similar and I had to shut it down via task manager too, but the log stated something about running 100+ ticks behind. That world is now completely unplayable and I hope performance gets fixed soon.

The same with 18w47b.

Affects 18w48b. This bug is extremely annoying.

Affects 18w50a. Why isn't this fixed yet?

Further "testing" (i.e. attempting to actually play the game normally) indicates that even pressing the close button on the game will cause the same effect, but with a black screen instead.

Confirmed in 19w04b and 19w05a.

Confirmed in 19w08b.

Still affecting 19w11b - I thought they had fixed this.

If this is still an issue in 19w12b, please provide reproduction steps.

19w13b: From spawn, try teleporting to 20 million blocks out on both axes. If stuff loads, then try teleporting back to spawn again, and then save and quit to title.
