I am in the US. I did a complete uninstall/reinstall of my game and launched it with my mods/saves/tray folders removed to the desktop - so its a completely fresh version of the game.
I do not have the Freezer Bunny rewards icon on my home screen but my husband logged into his account, had it, and was able to claim the first reward.
Attached is my log-in page as of now; you can see my only option is "new game" as my saves are not currently installed. I am happy to send any game files you'd like to review, please let me know.
I admit I am not keen on this whole concept but the fact that its not even consistently showing up for players and the launch itself was confusing for players because of the leak just makes it that much more frustrating.
Thanks!
