Earlier tonight I tested "right-clicking" to place items in locker. Clothes loaded into first row, but items would not load into item row.
Tried right clicking next set of clothes and it loaded to item row for first set.
Manually removed clothes and placed items in first row.
Right clicked on clothing item (metal facemask) and it left inventory but did not appear in locker or on ground.
Emptied locker, but item still not available.
Tried to pick up locker but unable to.
Filled clothes and item slots then swapped in and out on all locker spots, but missing clothing item did not return, nor able to pick up locker afterwards.
When locker "empty", hit with salavaged hammer, which returned locker to inv and missing clothing item appeared on ground in wreckage.
Issue is probably a FacePunch issue, and could be useful to hide gear items on a PvP server, but probably not intended.
