Kog"Maw Ult Kounter

Kog'Maw's ult, Living Artillery, no longer displays the amount of mana it would cost to use the ability. Kassadin's Riftwalk seems to be fine and I'm sure other abilities that are similar would do the same but Kog'Maw seems to be out of luck. This inhibits players from being able to know if it is worth using the ability agan or not so it would be pretty dandy if it was fixed very soon.
