Sideboard cards are (always) mixed, so (in bo1) i can't search with a tutor the card i needed because it's no longer in the bo1 pack
When i organize my sideboard in order to search, for example 'Scholar of the Ages' with 'Mastermind's Acquisition' in bo1 Timeless, then i play a game and 'Scholar of the ages' is no longer in the first seven cards so i can't search for it.
When i enter in 'Edit deck', the 15 sideboard cards are mixed together... I reorganize them many times but they always mix again.
I use PC and Windows.

Sideboarding in Traditional Pioneer with Yorion Companion
I was playing a game of best of 3 game of traditional pioneer ranked with Yorion as my companion (80 card deck). During sideboarding I only had access to the 7 "best of 1" cards from my sideboard rather than my full 15 (14 + Yorion) sideboard. I tried recreating the deck and changing the format around but I still had the same problems. This bug has persisted for a few months now. I was playing on the Steam client.

Sideboarding causes menu bar to turn white
Whenever I play a BO3 and have to sideboard, the menu bar at the top turns white during sideboarding and stays that way until I restart the client. In-game everything looks fine. But during sideboarding and when I'm finished with my match, it looks like that. Thank you.
