I've noticed that when I drop pod items into an outpost, specifically gear that can be equipped, if i try to equip them, they delete from existence. For example if I loaded up a drop pod with fancy new marine armor and sent it to a defense outpost, then tried to equip the armor on a pawn, it would simple disappear. It also unequips the current torso slot.

If I instead remove the pawn from the outpost, then take the drop podded item from the outpost, and then equip it, works like normal.
