Let me explain. I assume Gamekit goes and checks with the game if the user who sent the screenshot has actually reached the level that is shown in the screenshot cause otherwise anyone can photoshop a screenshot and change the level number that is shown in the picture. But if they do this then why is it necessary to send the screenshot in the first place? Couldn't there be a button to press when the user has reached the desired level to perform the level check instead of having to look at so many pictures?
I did the War Thunder quest and the progress is checked automatically with the game. Since Crossout is made by the same developer I assumed it would be the same way,
