TOPIC: Steam case bug

I opened a steam case, but accidentally pressed F4 and closed the F4 menu, it didn't give me a key or a game

Check your screen shots, it takes a picture when you open a case.

I closed it before it finished opening the case so it didn't give me a code or a screenshot. I've opened 2 and did this accidentally on the second one

Mine steam case is also vanised and some other people case also vanished when they try to open it. Do you guys run out of games or it is a bug? i am mining and if i got another steam case and it also get vanish then i will post again
