day 7 BONUS gone???

I finished day 7, but kept it open because it didn't had an expiration time
and I'm being attacked all day when im auto leveling.
Then suddenly my browser crashed, reloaded and my bonus is gone!
If it is a bug, I need some help to retrieve it's option.
If it did had an expiration time, there wasn't none visible on the claim page!
(if you compare it to the other day bonusses!) and you could read this an bug and complaint!

Who can help me?

I'm afraid Day 7 does have a timer on it. I suspect it had already expired and when you went to refresh, the game removed the Beginners Awards tab from your inventory.

It's logical it had a timer, but it wasn't visible:
by the other other days you could see:

..:..:.. hours to expire
