no 1.18.31 update available on switch
For who is getting trouble opening the worlds (app closes with error), maybe usefull check this:
MCPE-154306
With more time playing offline, I confirm that the world/map problem must have been solved with the Realms upload/download. I've didn't noticed any crash/loading problem since.
Nonetheless, trying to play normally, after some hours, the auto-saving lag/freeze problem appeared again MCPE-154110.
Some update:
When playing offline, in some ocasion that the world started, I've noticed the crash was ocurring in a particular part of the map.
I have there the main base. with a lot of chests full of itens and villager trade hall. And a "house" built in height...
I then played for a while +/- an hour in the same map that I previously uploaded on Realms (has I told before) going to has much as known places in that particular area, as other in overworld and some in the Nether.
I then downloaded again de world from Realms and I'm being able to play offline without incidents so far +/- 1h30m. It started ok all the times I requested. Saving and exiting. Re-entering. etc...
Seems to be stable.
The only thing I noticed was some lag (+/- 20 sec freeze) when opening some discovered minecart with chests in mineshafts (desert biome). Found 3 in a 30x30 blocks area.
Just to add that during the 15 minutes I played the game after the update, I registered a lot of lag, several few seconds stops in the game, and a lot of recording signals in progress.
As referenced by other users recently in other posts.
After 1.18.30 update I registered very large dificulties open my survival world.
80% of the times it gets an error at "creating terrain", and closes the app.
When sucessfully enters, after few minutes the game cracks and closes.
I managed to create backup vesions of the map, but all have the same issues.
I'm on nintendo switch version.
I've managed to upload the world to Realms and seems to be working fine on PC version.
On nitendo switch, some test and lighter (creative) worlds seems to go ok.
I too confirm that the freezing issue is a lot worse with 1.18.33
