In .44, there's a bug which causes inventories not to refresh. This causes a host of issues. The inventories/clothings that don't refresh cannot be used, looted, etc. They can forcibly be refreshed if there's a vacant slot to drag an item to, but this is only possible for the player itself. This heavily impedes looting because the only way to loot would be to take the entire article of clothing and try to refresh it later.

This also breaks weapons. If you pick up a firearm that hasn't been refreshed properly, it cannot ADS nor fire and often shows up with incorrect parts. This can be fixed by logging out/in and breaks combat.
