Hello! I recently started playing again and noticed something odd. I can't seem to cast any spells that would attack a single target. I can cast Mystic Colossus without issue, as it's an attack-all spell, but when I try to use, for example, Snake Charmer or my new Scion of Myth card (or even just a shadow-wand spell) it won't let me click on an opponent to cast it on. That meaning, there is no green 'check' in the cursor to signify it's even locked onto the target, and even when clicked nothing happens. Traps work fine. I have had enough pips, mana, and shadow pips to cast whatever spell each time but they still refuse to select.
Has anyone had this issue/is there something I'm missing with this new update?
