This crash happens also in 1.16.1. It is not fixed
On nintendo switch in local multiplayer (on the same console), especially with 3 or 4 players, chunks loading/generation is extremely slow in the overworld. Even walking is hard and also mobs or minecart are stuck in position when trying to move into unloaded chunks. My world size is approx. 300 MB, but these chunk problems are present also in already generated chunks with player relatively close (50-100 blocks) from each other. I also tried to lower the simulation distance to minimum and disable all video settings, but it does almost nothing. In the nether it is more playable, but even there the chunks load very slowly in multiplayer. This problem was present also in 1.14.X.
It happens also on Nintendo switch!!
I bought today minecraft Windows 10 edition and tried to play with Nintendo switch pro controller.
I confirm that this happens also to me. The problems i found are these:
The character can run with the keyboard, but not with the switch pro controller's analog stick, it only walks. I also tried to bind "run" to another button, but it walks only.
In the menus, it doesn't go seamlessly from a button to the next one if i keep the stick on one direction, i need press repeatedly the direction on the stick.
Furthermore, the "+" and "-" button are not recognized at all.
The other buttons work very well.
I have checked right now. Now the problem is resolved and the loop is gone!
Thank you!
