[BUG REPORT] Colorless mana doesn't stores

[jdmoralesp]

In the Android latest version, whenever I tap for colorless mana previous to casting a spell, the mana doesn't go to the mana pool and is lost, for instance, this also happens for extra mana, for instance casting a sensei's divining top with a sol ring doesnt let a mana in the mana pool. This happens only for colorless mana, for any color is fine...
