Prior to the update their were issues with this, and they still persist.

This week I got the rare warrior, magus & sentinel souls from the store via trooper points. However, the only soul that shows locked is the gun/assassin soul -which I did not yet get. So I figured I'd try to get the others again since they are not locked, but when I attempt to I get the message "Your purchase failed, please try again."

Please help. Nobody wants to grind in vain. Thanks!
