UPDATE !!! THIS BUG IS HAPPENING ONLY WHEN THE TARGET IS IN TALIS MODE, but when the target is not in talis mode the script is working fine.
My Single Strip is Bug here is the scenario:
Player 1(stalker in talis mode): Use Single Strip on Player 2, After player 1 stripped the item of (player 2 in talis mode)
Player 2(any job in talis mode): stripped already, but you can equip the item again.
THIS BUG IS HAPPENING ONLY WHEN THE TARGET IS IN TALIS MODE, but when the target is not in talis mode the script is working fine.
to make it short after you Single Strip the Armor. the other player is stripped but he/she can equip it again after being stripped.
