local variables got removed after delay effect

[MellDa1024]

Describe the bug
local variables are removed when 'wait n tick' is executed in other listener while the delay effect is running

To reproduce

effect npc wait:
	trigger:
		broadcast "npc wait"
		delay effect
		broadcast "npc wait - delay effect"
		wait 40 tick
		continue

on right click on entity:
	if clicked entity's name is "TestNPC":
		set {_name} to "TestNPC"
		add "Dialogue1" to {_dialogue::*}
		add "Dialogue2" to {_dialogue::*}
		add "Dialogue3" to {_dialogue::*}
		add "Dialogue4" to {_dialogue::*}

		send "%{_name}% :: %{_dialogue::1}%" to player
		npc wait
		send "%{_name}% :: %{_dialogue::2}%" to player
		npc wait
		send "%{_name}% :: %{_dialogue::3}%" to player
		npc wait
		send "%{_name}% :: %{_dialogue::4}%" to player
		npc wait
		stop

on right click:
	broadcast "1 tick start"
	wait 1 tick 
	broadcast "1 tick passed"

here's a code snippet. (My original code was over 3,000 lines long, so I removed unnecessary parts until I could reproduce the bug)

1. load this snippet in server
2. create npc named "TestNPC"
3. right-click the npc

Expected behavior
local variables should remain
