The same thing started happening to me about two weeks ago.
It tends to happen at my base where there are a lot of chests, villagers, etc., and most of the time it happens when I'm accessing various chests to organize my belongings.
Also, nearby villagers have disappeared and new children have been added.
Once disconnected from the server, I work around this by downloading the latest backup once, organizing my belongings locally, and uploading the data.
My world is about 280MB in size.
I hope this problem will be solved as soon as possible and the money I am paying for the subscription will not be wasted.
