All of my credits disappeared

[rlndsznt]

I won 120 stock credit last year while participating in one of the Adobe Live design challenges. There was no expiry date for these credits.

I still had around 80 about 1-2 weeks ago when I last checked. All of them disappeared now. Why did this happen?

Credits have an expiry date of ONE year. That's at least the standard expiry date I will suffer of.
