Collectible Card Game Headquarters

Describe the Bug:
When I copy a "fireball" with a "fork" the copied fireball mana spent is 0

Which card did behave improperly?
The copied fireball should have the same amount of mana than original one

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink updateago2016 Eldritch MoonV2 - gauntlet

What exactly should be the correct behavior/interaction?
If I cast a fireball of 3 and I cast fork... the "forked" fireball should do 3 damage too. Currently the "forked" fireball do 0 damage

Are any other cards possibly affected by this bug?
Probably other cards with same mana dialog menu like fireball

I confirm this.
We had other reports about fork and copy spells with X not working correctly but I don't think it was the same problem as this one as they didn't copy the x value. This seems like you get to cast another Fireball instead of copy it as it calculates the available mana for the copy so you can pay as much mana as you have for the copy or 0 if you don't have available mana which is your case. Also the same happens with Dualcaster Mage that I tested.
