The trident was thrown by the owner.
The player that created the Realms. The one, in the example, that leaves and then re-enters.
Thank you
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.
I too confirm that the freezing issue is a lot worse with 1.18.33
