Sooo...
I did just a couple of tests....
And here are the results of the observations:

To begin with, because I remembered that in the previous version of the modpack and mod everything worked without problems, I created a duplicate of modpack, and created a new world. Everything worked fine there.
This confused me.
I created a duplicate modpack again, but this time I copied it along with the worlds. In the old worlds, it didn't work and the content was lost when you re-loged:

Next, I created a new world in this duplicate modpack, and it worked there, but sometimes misfired:

// The strangest thing is that according to these screenshots, I thought that it was an upgrade issue, and put drover without upgrade in the same place, and a control one with an upgrade on top.... and.. nothing happened....//

I continued my experiments, and went to the original modpack and the old world:

1. old world but different place in the world: No change

2. I decided to check what happens if I put the drovers in the old place (where they were before I updated the version of the modpack and mod, respectively):

I was interested in the fact that some of the content remained untouched, and I decided to test the hypothesis by putting drovers at the junction of chunks, one of which previously had drovers.:

The hypothesis was confirmed : The content was lost only in the chunk, where previously there were drovers of the old version of the mod

//Although it is strange that it works every other time//

I apologize for so much text and screenshots. But I tried to check all possible cases, and gather as much information as possible.
