The original day 5 quest was to craft a chest guard. As many pointed out there was a high random factor involved, so thankfully Tynon changed it.

However, there seems to be a lot of players completing The Horseman and not getting their beginners rewards for doing so. Hopefully it's a small relief to know you're not alone. Since there is an issue I have faith Tynon will sort it for you. What I can't do is give a timescale as I'm not employed by them.
