Hello, i add scroll to remove time from instance but i find a `bug`. I don't know if to call this a bug. But i add reuse 3 hours of scroll. But player can restarts his character and if he buy scroll from shop again, he have reuse 0. I can solve this by xml? This is xml from item.

 

<item id="23047" type="EtcItem" name="Instance time remover">
		<set name="icon" val="BranchSys.icon.br_xmas_miracle_i00" />
		<set name="material" val="PAPER" />
		<set name="is_tradable" val="false" />
		<set name="is_dropable" val="false" />
		<set name="is_sellable" val="false" />
		<set name="is_stackable" val="true" />
        <set name="reuse_delay" val="11000000" />
	</item>
