So... I've used some of my reward points/units for:
  • Assassin Killer Outfit (Cost: 20U)
  • Katana and Wakizashi set (Cost: 30U)
  • AC Rogue Theme pack

However, this is apparently unavailable in-game (I've tried from the captain's cabin in the ship & from the general store) - it just says 'redeem on Uplay'. I've gone to 'additional content' to see if I have to download these items, but there's nothing there.
The only thing I've been able to download/use is the Theme pack.

So, I'm 50 or so units down and I've got nothing.

I've also completed at least one action (Complete Memory Sequence 1), and haven't received my 10 units for it.

Help, please?
