I sort of had a work around....using realms. I uploaded the PS4 world to realms, downloaded to my PC running the bedrock world and had not issues with leaving nether and back. I then uploaded from PC via Realms back to PS4 and it seems to work...A bit convoluted however at least I now have even more different back ups of the world....
I am now playing in realms as it actually seems to run faster/better than the PS4 pro I have...Almost zero delay in portal teleporting.
This also is happening on the PC version. I use realms to transfer my PlayStation world to the PC bedrock version and got the same "block/chunks" missing. The delay was less however my laptop is quite a bit faster than the PS4 so it must be something more fundamental.
I am now having the same issue. One of the crashes even corrupted my save game. I have been experiencing issues with a general delay when using the portals over the last few updates. It is really quite bad now. I will try the save and quit while teleporting to see if that works as I also have on occasion ended up in the overworld after a crash...
Version - Playstation 4.
There was some comments earlier about throwing objects through the portal first, a few seconds before you travel through. This seems to be working for me on the PS4. I am still making backups/copies before I travel through and one sequence of pass throughs I ended up over 50000 away from base....Easire to just trash the copy and go back to an older one.
Process
Save and exit
Copy current world
Load current world
Through apple through portal
Wait 3 seconds
Go through portal
Success - continue playing
Failure -
Drop out of world,
Delete current world,
Rename pre-portal world copy to current world name
Copy pre-portal (now current) world
Load current pre-portal world
Try again
A lot of faff, particularly on a PS4. but still better than either suffocating to death, void or 50000 blocks away.
I am having the same issue with named villagers in minecarts . I am traveling hundred of blocks and back again. Gradually losing all the villagers in my iron farm. They are all protected from lighting, in minecarts, named and I am and have only been playing on peaceful.
Can be very annoying if you get the perfect trade...
Not sure how this links to the invisible ticket it seems to be associated with but as I'm on PS4 I dont have an F3 to see if the entity is still there...
When running the same world on realms it seems to behave a lot better. Have not experienced the missing block issue yet in realms - it seems to load the chunks differently/smoother?
Something very odd with file sizes though. On the PS4 it is 950mb. On the laptop only 500mb. Could not see anything missing after traveling around a good part of my world...Even when I transferred the 500mb world back to realms and then to PS4, it became 950mb again on PS4.
