Problem z wait

Witam

Mam problem z tym skryptem 

on rightclick with eye of ender:
	if player's tool is eye of ender of unbreaking 10 named "&cZamiana":
		cancel event
	if {polimorfia::*} is set:
		send "&7[&4Zamiana&7] &eJuz jestes zamieniony"
		stop
	else:
		run player command "/disguise zombie" as op
		add player to {polimorfia::*}
		set {_time} to "%{czaspolimorfii.%player%}% minutes" parsed as time span
		remove 1 eye of ender of unbreaking 10 named "&cZamiana" from player
		wait {_time}
		run player command "/undis" as op	
		remove player from {polimorfia::*}		
		stop
	
on death:
	if {polimorfia::*} is set:
		remove player from {polimorfia::*}
		run player command "/undis" as op
		send "&cZgninoles! twoja zamiana zostala zdjeta" to player
	else:
		stop		

mianowicie chodzi o to jak zrobić gdy zginiemy to dalsze czynnosic po "wait {_time}" zostana zatrzymane i nie zostana wykonane?
