New Engine bug?

[ApothiX]

I was writing a script the other day, and couldn't figure out why it wasn't working. I was attempting to call a public function stored in a WNPC but the problem was, I had a DBNPC with the same name, so it was attempting to call the functions from the DB NPC. I then copied the code from the DB NPC, created a new one with a different name and deleted the old one. The script still failed to function. After an hour of frusturation, I tried creating a new WNPC with the exact same code in it, with a different name and the script worked flawlessly. I think there is a bug in the new engine that is preventing the deleted DB NPCs from being taken out of memory upon deletion.
