When picking up items, the Volume limit in the top left, if increased by a digit then reduced, will add an extra digit to the limit displayed.
ie.
Vol 68/102
Then highlight a corpse for pick up
Vol 143/102 'The number has more digits
deselect the corpse for pick up
Vol 68/1022 'The number was reduced, but the final digit was not removed from the display
No gameplay difference but a little thing I noticed.
