So a couple days ago I received the Tirpitz as a rental for 48 hours, along with a 50% off coupon to purchase (that expires 4 days from now). I've thoroughly been enjoying my time with the ship and wanted to purchase it from the premium store. However, I can't for some reason. The 50% off coupon shows up in the coupons tab, and shows that it still has 4 days remaining. However, when I click on the coupon, it just says this category is empty, implying that the coupon isn't valid for anything. Furthermore, when I click on the Tirpitz in the store, the option to use the coupon isn't there. It just wants me to pay full price. Am I doing something wrong? I've sent in a ticket but I'm worried that by the time they get back to me, the coupon will have expired. Any help is greatly appreciated. Thanks!
