We’re currently looking into an issue that is preventing
some players from receiving the Deadly Assassin’s Outfit after
correctly inputting the code. If you have received a message in-game
that the outfit has been successfully unlocked after inputting the
code, it should eventually be added to your Outfits menu where you can
view the tasks you must complete before you wear it. It make take a
short while to appear though as the servers being used for handling
this update are receiving heavy traffic.
If you have completed the entirety of the "American Appetites” quest
before you gain access to this outfit, don’t worry – you will still
receive credit for having completed it and that task will be checked
off.
If you’re having trouble finding Mo Van Barr once you’ve
successfully downloaded the Deadly Assassin’s Outfit, a Wanted Poster
for him should appear on the side of the train station in Armadillo. It
may take a few visits for it to appear though.
We’re working hard to get this sorted out for you guys and totally understand how annoying this could be.
