Here is an idea add this to all putnpc2 npcs
NPC Code:
join npccontrols;
Then make a class like this
Class name = npccontrols
NPC Code:
if(destroy) {
destroy;
}
Then make an npc weapon that calls all npcs in a level with the destroy flag that way you can clear levels easily.
*Just a suggestion to prevent future problems or you can use the rc to clear it*
