Ever since the last patch I have had several instances where the Demolitionist grenade launcher does nothing. It launches the grenades and uses the ammo but the grenades do not explode and do damage. In order to get it to work again I have to completely shut the game down and restart. This usually happens in the middle of missions, it works fine the suddenly does not.
Here is a link to game play video showing how it doesn't work
