In warlords, if you order something from "Gear" category and it gets destroyed due to collision while landing, the game will completely freeze. The only way out is to manually end the arma 3 process. One way to reproduce this is to:
Get a vehicle
Order a vehicle ammo box
Drive your vehicle under it while it's landing
Wait for it to land
As soon as the game freezes the rpt log gets spammed with
13:47:24 Error in expression <}, {_i = _i + 1}] do {
if (((_itemsPool # _i) # 0) == _itemType) then {_itemInde>
13:47:24 Error position: <# _i) # 0) == _itemType) then {_itemInde>
