I played Buried Treasure with 4 untapped mana remaining. Theoretically I should have been able to tap Butied Treasure to add 1 Mana for its Pay 5 effect and use its effect in the Graveyard to discover. Problem is, the game detected I had no moves and skipped my turn. I of course lost immediately after. Please fix it so that if it detects 4 mana and is untapped, it can use its effect.
