Deck builder won't let me save deck due to sideboard bug
Deck builder says I can't save a deck with more than 15 cards in sideboard even when the side deck has less than 15 cards. It forces me to go down to 7 cards in the sideboard to save. This is for a standard deck.

Invalid sideboard
Almost all of my decks are now invalid and unplayable because of an invalid sideboard error. No banned cards, or more than 15 cards in the sideboard. I can't even edit and save them because of the continuous sideboard error message.

Cid rimeless
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

Invalid deck error
After the newest update, my Standard deck is invalid due to a side board error. It says I can't have more than 15 side board cards but you can see in the image that it is 60/15.

Cannot have more then one copy, Brawl bug.
I have five decks that are no longer valid in Friendly Brawl because they contain multiple copies of cards that should allow it. Eg: Rat Colony, Persistent Petitioners, ***** Against Humanity, Nazgul, Hare Apparent.

Brawl states I have too may copies of a card that states i can have any number of copies
I have cid timeless artificer which states I can have as many copies in a deck as I want, but when I try to play it it gives an error that I have too many copies. If I remove them all and replace them with something like islands its fine, but if I add even one extra it gives me that error

Set Completionist II
Set Completionist II not giving me credit for completing the Final Fantasy set. Please fix this, I spent so many Rares and Mythics on this. My only thought is FF of the Ages is also required, and if so, then its very misleading... Yes, I have 4x of every card in the Final Fantasy set, but not FF Of the Ages.
