Lucky or bungie wanted a good laugh

So I have been saving up my strange coins for some time now and finally had enough to buy my first exotic piece of armor almost enough for a weapon but decided I wanted the armor more. Anyways skip forward a few hours in the day and several strikes and have quite a few engrams. Take them to the engram guy and get nothing special but I do level him up. I see I have a message full of new goodies and one is a legendary chest piece. I was pretty stoked since that was the last piece of gear I needed to have full legendary. Go get it and it turns into a exotic piece. Yeah that's cool and all but now I want to use my chest piece and I don't have my legendary helmet I had before my exotic one. Not only that I could have saved my coins and bought a weapon and had my two usable exotics... talk about first world problems Anyways need more raid friends also add me T8erTot89
