After selecting one perk instead of another or selecting a perk for an empty slot, the perk you selected is not updated in the perk window (bottom left) until you reopen the window.

Visual bug when selecting a cell with perks. If you click from one cell to another, the green frame on the previous cell remains and is not removed.

The perk doesn't work well and is somewhat inconsistent.

a) Sometimes the perk simply doesn't work; it works once and then doesn't work if the player dies while reloading.

b) The perk only hides the player, but not their weapon.

c) The perk hides the player but doesn't allow them to pass through other players and props.

The perk on the shield doesn't look very good when spawned.

5. Sometimes, when you click on a perk in the perk menu, nothing is selected and nothing happens. It helps to quickly move the mouse pointer to another perk and back, and then it will be selected.
