Quest giving rewards for craft and loot before turning them into NPC

Quests are running commands to grant rewards and also announcing in chat before they are actually completed. My quests are configured so that the items crafted/looted should be physically delivered. It's misleading to players to announce that quests are completed before they've actually been turned in.

Example configs:
