Not a bug. This is the interaction of layers of continuous effects. Type changing effects happen in layer 4 while ability losing happens in layer 6. Since effects are applied in the order of the layers, Magus of the Moon and all other effects that include a type change (like Ashaya, Kaito, Kudo, and many others) always happen before the ability creating the effect is removed. They always win out over ability losing effects. And due to rule 613.6, once an effect starts to apply, it gets to apply fully, even if parts of the effect happen after the ability creating the effect is removed.
