Immediately after opening my last free booster, another one appeared. When I try to claim it I get an error. Retry does nothing, cancel stops the purchase, but the Free Booster is still there red dot and all. I hope this doesn’t prevent any further free boosters.
Did you encounter the Booster Crafting error? If you did, then numerous aspects of your account will no longer be updating correctly. Please send a support ticket in, and Customer Support will be able to escalate it so a manual fix can be applied.
