I also encountered an issue that happens around the same time when the same issues you desribed happen which is mob ai freezing and not moving at all. Relogging does seem to fix these types of bugs but they later apear after some time of playing in the world. My affected platform is the ps4.
Whenever the button combination thing doesn't work, make sure to close Minecraft and reopen it and then do the combination again. This worked for me personally.
After 4 months of this bug's existence, it's still contaminating us. After pressing the evil uninstall button and then reinstalling, it still manages to hurt us. All fellow gamers, we most unite to end the mojang infinite loading screen and put a stop to this pain! Except that only mojang can stop this and they will haven't resolved this issue even after 9 bug fix updates.
If your world was made on bedrock edition then no but If it was on legacy edition then later converted to bedrock then You can search for the old save and reconvert it.
I might be very wrong but judging by the fact that we on bedrock have less grass and kelp generation compared to java, this might be intentional? Hopefully that's not the case because boi this sucks.
This sometimes happens randomly on my ps4.
I remember one time, I got my save corrupted after the power went out and I couldn't recover it because there were no backups, so You better start making backups!
I cannot help you recover your world but I recommend ALWAYS making backups whenever playing on your worlds.
These are called Cave Ambient Noises and they usually play whenever there is a dark place in your vicinity. These noises have been added on the 1.16 update as a parity change but sadly, there is no way to disable them at the moment so try to get used to them.
Does anyone understand me?
Because the regular planks when you get it from commands, you use:
/give @p planks 1 1
/give @p planks 1 2
/give @p planks 1 3
/give @p planks 1 4
/give @p planks 1 5
/give @p planks 1 6
but to get the Crimson and Warped planks from commands, you use:
/give @p crimson_planks
/give @p warped_planks
not:
/give @p planks 1 6
/give @p planks 1 7
When you take Warped and Crimson planks you should use /give @p planks 1 6/7
Not /give @p crimson_planks
/give @p warped_planks
Sorry, I didn't know it was a duplicate (MCPE-74339)
Thank you
I know, but I don't know how to make it New Feature
(It Isn't A Bug, It's A New Feature)
This issue STILL exists, it always have been and I don't recall seeing an atempt to fix this bug.
Steps to Reproduce:
1. Force the power to turn off from the ps4 while playing within a world.
2. Play within your favourite world and hope for a random power cut, maybe from a storm, the ps4 will shut down.
3. Shut down your entire house's electrical power while playing within a world on a ps4.
Observed Results:
After turning the console back on and getting in Minecraft, clicking your world/save would showcase a menu telling you that the save file has been corrupted. Bringing it back is rather difficult as it requires ps+ to already own such save, or doing some tricks that hardly ever work.
Expected Results:
After turning the console on and clicking the world save file, it'll get in the world fine and you'd be able to pick up the game where you left from.
