Recently discovered there may be a relationship between using the destiny promo code for the Gjallarhorn Grimoire card and never getting the actual Launcher to drop. Many people in the forums seem to be having the issue of using the promo code that was available when destiny dropped to obtain the grimoire for the launcher and still not getting the drop. This poll may help figure out if there is in fact a bug attached to the card and promo code. (given that people actually answer honestly)
