[Darkhero06 0]

Basically have the issue stated here https://github.com/TrinityCore/TrinityCore/issues/15931. When I purchased BKP "Impact" shot from trainer it doesn't show up in my crafting page to craft it and when I go to trainer and look at already purchased when mousing over the picture which is supposed to be impact shot bullets it says its a Glyphed Breastplate. So I can't make the bullets. Here are some screenshots. http://imgur.com/a/yoeaS
