I have already sent an email to Kiel's support with this information. Yesterday night in my country region (Brazil) I got my daily gift as usual. But when I went to check the new drop 'Pheonix Shoes' I didnt find it on my recent discovery window or even in the curios tab.
So I sent Kiel a sup ticket asking for help.
Today morning I have the idea to search for the 'Pheonixs Shoes on my Steam DST inventory, and IT was in there.
Somehow Steam registered the Pheonix Shoes, but the game did not.
I know it's a silly bug, its definitely not that amazing RARE shoes anyone would like get, but still it can be unravel for 45 spools.
