This is a problem with using the mouse to navigate your characters movements instead of the keyboard. When running downward using the mouse and the left mouse click button and attacking with the right mouse click button, if the player accidentally skims over the vitapod icon with the mouse AND is attacking, the right mouse click will pick up the vitapod health and drop it on the map. This happens often if the when I am swamped by enemies, and although a human error, it is annoying nonetheless, especially if it occurs during near full health when facing a boss. upon re-equipping the dropped vitapod, health is not recovered, only health slots.
Lock the HUD using the 'q' key(or what ever you have it set to). Use the same button to unlock.
