Because there are a lot of ambiguities associated with frames rewards for the anniversary event, it will be a good idea to write specific and clear conditions how unlock them.
Maybe you guys can write it on forum or better, in news section on yours website?
For example: In game you have description like “drink all ale”, but on website you clearly write - to unlock this you must drink X (where X is a number) bottles of ale that you can find on map.
