Reset all instances

[schopen20]

Hello, friends. First sorry for my English. I would like an npc that resets all instances of the game. For example, I really want to reset the horror factory instance, but I can't find anything to solve my problem.

Please, help me.

if (checkquest(xxxxx) != -1) {
    erasequest xxxxx;
}

find the quest id that are used for quest cooldown.
