Alright so my problem is that usually I am able to create an NPC then reload the tables "creature_names" and "creature_proto" right ?
Well every time I put a new NPC in my DB, a restart is required in order to spawn it in-game.
It really gets in the way of my server's development process and if somebody can figure out whats wrong and recommend me a fix then he will be doing my server a great favor and +rep of course!
