While checking in on my screenshot verification for Rift, I noticed that my point total was somewhat inflated; namely, I had more than I should at that stage. I quickly browsed the notifications and saw, to my surprise, that I'd been provided credit for Quest 3 in World of Warships ("Fight 2 battle with 2 more Tier 3 ships") despite having only fought with one more Tier 3.
I believe the error stems from the use of my Tier 3 used to complete Quest 2 ("Fight a battle with a Tier 3 ship") when I participated in another battle with it while waiting for an unfortunate loss to resolve.
I have since spent nearly three hours in World of Warships amending this oversight by farming my way up to the acquisition of another Tier 3 and fighting with it, as you can see in my screenshot below, thus I am entirely deserving of these points; nonetheless, I thought it best to inform the GameKit staff that this error has occurred and may occur with other accounts as well.
So: be aware that the Tier 3 ship you use to complete Quest 2 may, inadvertently, be counted toward your progress on Quest 3 as well. You should continue to play until you've actually fought with THREE unique Tier 3 ships in the game.
Thank you to all the GameKit employees and volunteers, along with the fine people at Wargaming and Lesta Studios for providing us this game...
