Thanks for the suggestion.
I have failed to find a support route, so do appreciate the link provided, however, I do not use Discord, and do not feel I should be required to in order to play a game purchased (I do not socialise with the kids, other than relatives/friend's kids).
Tutorials/wikis are all stitched-up too...
In any case, I reported the fault here, and hopefully a fix will result (I won't hold my breath).
What I am experiencing, to my mind, is a bug/error. Hopefully this has been reported to the correct forum.
Thank you for the reply. Do you know if this issue is known to Mojang? I have seen similar threads dating back years. Do you have any information as to why I am now affected?
Resolved. I had not cleared the game save data on console since returning to my original router/network. After rejoining the original, I should have re-synced. I thought I had, but was pretty fried after all the network testing.
The last time it was done was when I was testing the new 4G router, which synced the cloud on that new network (although it did not work on the 4G network, and I carried the error sync back to my original network).
Not a 'bug' as I thought. Apologies. Maybe this might help others?
