I bought it 4 days ago and still haven't received anything. Looked it up to see what was happening to find a post similar to this from someone who had purchased it 5 days previous with numerous people saying they had the same problem. Ubisoft just keeps saying to make a case and that they are looking into the problem. No one wants to answer why they haven't removed it from the store until resolved, or placed a warning in the store or in game, to warn potential buyers, rather than promoting it's purchase.
Notice how they only want to respond with "We are aware and are working on it"? They still won't answer why they haven't removed it from the store, or put a warning on it in the store or in game instead of promoting it's purchase still knowing there's a problem. I even asked if the problem only started after the cut off date for the weapon skin and didn't get an answer about that either.
