The pictures helped btw, the support account will be writing you about it. Your store pics show the store is not seeing that you own KI Anniversary Edition, which we know you do, so that is a problem- the store issue needs to be troubleshooted. They will help you in the direct message thread.
Note- I am 56, these are my instructions the team is following, so it would be 'Gen-X’rs…" not ‘Milenials…’ 
We will get this figured out!
All the actions that I performed at the request of ““support”” looked stupid and this did not bode well.
Well… i was right…
I did everything that was asked of me. (including updates, and other crap)
And as a result… What I was so afraid of happened. I completely lost my progress.
Thanks Jim!
I’m now back at level 1…
Everything was gone except the KI gold and shadow point.
Story mode… wanishd.
my 106 percent over the years… - down the drain…
Shadows and Mimics expressions are not owned.
Even the progress from the shadow lords has also reseted (although it is also on the server!!) and offers to create a new team.
I’m even afraid to guess, but I think if I create it, I will have neither guards nor progress.
Please tell me that this is something you are changing now and you can roll everything back.
Oh yes. We have a topic about offline. “Sheet” doesn’t work! For several years I was even afraid to use my main account because of glitches that arose and I used a second one so as not to lose progress. I won’t even try the second one now.
Oh no! Were you trying to play offline when this happened? Was there a save sync warning?
We do have tools to help with some progression fixes. Your save game is what is tied to that stuff.
Support account will reach out and continue to work with you.
So it not becasue of you make some change…
No il try online after Upadete xbox\store, log of and logon. And sync warning appear. and i selecr Local(newest)… 
Actualy i was afraid and hate this warning all this years…
To be more precise. There are two changes. No. Aniversary still does not show the Owned status.
But when I hover over it with the mouse, it shows an Open button.
KRAKENJIMMY will be reaching out to help with progression through direct message for further support.
Thanks for confirming you saw the warning, this is something to be wary of - the advice is quit and never choose (local/offline). This is a risk with going offline/back online and I know that is not helpful to hear right now (this is for others reading) and I really feel bad this happened
Let me say please do not try to do any more offline/online stuff with your other 2nd account. If you see a save warning there, quit do not select offline/local. My advice is stay on this account that lost save progression until we work through things.
So I am going to take over helping you directly in messages.
As for getting your store to work so you can see you own the title on this (affected) account first, I will work with you on this if you still want to pursue getting that to work.
Then I will rebuild your progression on character/player levels.
I will get you resources to buy back missing shadow/mimic skins.
There are other things I cannot fix, we will work out what we can at least do.
I will write you directly shortly (30 mins or so).
Will wait. I am in touch.
Do you know what’s ironic?
It was because of a “similar” situation with synchronization that I stopped using the main account. It just endlessly said that it couldn’t synchronize and I was afraid to choose. And so I abandoned it for several years. Until I accidentally got a second account.
I sused the main one only after we started all this. 
And everything seemed to be going well.
Today - is not my day.
