Brawl not accepting Hare Apparents?
Just got the new update, it cancelled out my Aerith Brawl deck initially for 19 cards not accepted. Built a new one thinking it might be because of the rotation of sets. Turns out, it was an issue of there being more of the same card in the deck (Hare Apparent) although the function of Hare Apparent allows for more than one of them in a deck. The deck had worked before the updates. What's changed?

Arena is telling me that my Cid deck is invalid because I have too many copies of Cid Timeless Artificer even though it was working just fine yesterday and Cid's card literally says there's no card number restriction on him
