Still Haven't recived the Syndrom Boltock!

So after claiming it I thought it was just a server thing but everyone else got their skin?

As a suggestion, take a screenshot next time you have a problem claiming a reward, that way no one can question the validity of your claim (it was actually a suggestion given by TC on the esports streams last year, before they changed the system where the reward was credited to your account in a matter of minutes).
