NPCs Don't Drop Loot

I just compiled a TrinityCore it's up to date at 3.3.3a and has ACID support but I can't get the NPCs to drop loot. The only one that I've tryed that has dropped were the wolves outside of Elwynn forest but everything else doesn't drop including the bosses. So anybody have any ideas on how I would go about fixing this. :o

did you killed them with command (.die) if you did, you can fix that in the TrinityCore.conf

If not, update your database.
