Some unlockable skins have been reset after this patch

Here’s the issue, i had this bicolor desert skin unlocked (i got a total of 149 kills in sim GF) on the SA342M Gazelle before this update.


After this update it says that I have 0/600 score to unlock this skin, and i basically have to start over.

What is going on, do devs understand how to keep account data ? Or is that deliberate ?

Edit: It also affects Tiger HAP, Alouette III skins
