Healing booster is no longer increases Viscious's cube's healing

[Dezvul]

Ok, so I haven't played since the day before Mirage came out and I'm just getting back into the game, but I know I've tested healing booster before and it used to increase the healing of the cube. This is no longer the case. I've tested in game and I've tested in the hero sandbox and healing booster is not increasing the healing of the cube anymore.
