Bug NPCs crashing server

[Newstart]

Hi, I'm new to the private servers and all, and I got my server up and running with out a problem. How ever, I will happen to spawn a "bugged NPC" once in a while (one was Jaina Proudmore, and the other was Scarlet Commander Mograine, one in undercity, other being in SW where king wyrnn is) the difficult thing is trying to get rid of them, cause I can't reach them from game with out crashing the server again. What can I do to remove them from the game through an outside program (I.E. MySQL, Navicat, etc)?

Hmm, is it your own private server or some other server? Please be more specific.

yeah its my own, but I cant make it public, so idk if that makes it harder or easier.
