Delete your tweaked spear, then get -=>RR<=-MasterCE's spear.
If you want to make your own spear, copy spear.cs to your desktop or somewhere else besides Add-Ons. Then go into it and press Ctrl+H. In the first box, type in spear. In the second type TweakedSpear. Now press find next and then replace, but make sure not to replace textures or sounds. To be safe, dont replace anything that has /Base/Data in it.
