when players have an upgraded weapon they can take back their materials by canceling the upgrade of their weapon. let me give an example:
I have an m4 that is lv.4 and i have another weapon that i want to upgrade so i can go to the m4 and you can cancel the lev.4 upgrade level by canceling that level the m4 will go back to lev.3 and the materials that were used for the level 4 upgrade and paint will go into the inventory. PLEASE PUBG ADD THIS PLEASE ITS GONNA BE INSANE PLEASE!!
