I experienced a bug several times after sideboarding with a Companion deck (Keruga). The new state of the deck won't be saved, cards I sideboarded out are still in and new cards are missing.
Steps to reproduce:
Build a deck with Keruga as a Companion and make a normal sideboard. (I can share my decklist if you want)
Play a game
Sideboard
See the cards that should be missing
Wonder why there are no sideboard cards

Expected Result:
Should be obvious, right? ;)
