go to items.qc in folder .\NOHRP and find void () item_artifact_multiprojectile. open it in any text editor like notepad.
add this line to the function:
self.classname = "item_artifact_multiprojectile";
then find the function void () item_artifact_super_damage2 and add this line:
self.classname = "item_artifact_super_damage";
then run qcc.bat and you should be good to go. if not the powerup will not work in the maps you find it. something to do with randomly spawning powerups, and the classname not being registered. this fix will be in the next patch.
