I can relate, the inventory is very difficult to navigate especially to new players.
1-lag is very bad when near more than one inventory and attempting to view the inventory menu.
2-Game crashes when you navigate the vicinity inventory if the storage unit is very full.
3-Items can't find a place in your inventory when picked up from vicinity if the "pocket" had previously been full "occasionally"
4-Items disappearing from inventory after server crash or reset, even though item was NOT a recent pick up. "In hands inventory"
5-"not a problem" I had to mention this, we have a Belt equipment slot but no belts, so a pistol holster and belt would be great also the attachments for the plate carrier. I'm only mentioning this because the extra pockets would help alot, the assult boots with the knife slot actually made a huge difference.
