Durward Codec Online

That's right @V3ct0r, it really was outdated.

Usually the main gameserver brings with it many important settings and for this reason it is not good to restart. If you need to frequently restart some maps, I suggest placing these maps in another gameserver (outside the main), so you can restart the gameserver responsible for the map you want, without having to restart the entire server. Maybe there's some command to do this on the gaming server, but I've never heard of it.

Why do not you try to delete it from the map by the resource? This problem can also be that you have confused the numbers of attributes and the like at the time of editing this monster in the characterinfo. If the monster is not generated this way, most likely this problem is being created from a bug in your resource.
