A me succede solo con i deck che contengono il compagno.
Se non risolvono il problema credo che smetterò di giocare a sto gioco pieno di bug(se la combatte con fallout 4 e ho detto tutto!!!)

I Play on a virtual Machine and encounter lots of crashes these times. When I reconnect, I cant sideboard. None of the buttons work, the timer does not move, Deck name is weird, and it is impossible to exchange cards (my decklist isn't even appearing)

I expected this bug to be corrected in the last update on April 30th, but still got the problem. It happens on EVERY BO3 game I make with a companion, and I lost so many games to this. Hopefully I found a great workaround : I only play BO1 matches.

Same problem here, however the game never returned and it got stuck in the sideboard area.

Same problem. Lurrus as my companion, bo3 traditional standard: went to SB and the timer wasnt moving and it wouldnt let me press the accept button aftermaking my SB adjustments. Timed out and went back into game without the changes I had made. Same thing happened between the next game.

Had the same issue in standard ranked bo3.

Same problem with my Keruga deck.

I had the same problem

Same problem here, with a Yorion Deck.
Seems to be occuring when playing companions.

I cannot see my maindeck and companion, I can only see my sideboard cards. When I try to click on them, they disappear. Done button also does not work while timer is frozen.

the same

yup happened to me too, guess it's an issue with having a companion in your deck. Definitely lost me the match too

Happened with me too, attempted to sideboard during the metagame challenge and my sideboard voided out. Super frustrating, I was up a game and probably would have won if I'd been able to sideboard.

Quick edit, I was using Lurrus and a Rakdos deck. I boarded in mayhem devil and midnight reaper to make my deck more sac-y. This should be legal, but the sideboard failed.

Hi!
Had the exact same bug, my companion seemed to be all wrong as well (it was Umori, the collector). Getting Umori out of companion/commander slot seemed to fix the issue, but I was still unable to save any sideboard changes.

Was not able to make sideboard changes after a crash. I was also playing in the arena metagame challenge. Compensation for the game would be appreciated.

Happened again to me, after this occured during draft, now during the metagame challenge with Yorion as companion I couldn't side anything and submit the deck. I had to wait the timer whitout doing anything. I was up a game and this happened both the times, after game1 and 2. Lost my match this way.
Hope we will get a fixing.
Thank you.

Getting this issue quite often with my Lurrus deck. The last time it cost me the second match in a standard challenge event...

This happens everytime after a crash, regardless of the companion (same problem with Keruga). if you remove the companion, you can see the deck again, and do the sideboarding, but continue button is disabled, and when the timer goes off, the sideboard is not submitted.

Just happened to me as well. Been happening off and on

After restarting client I am unable to see my main deck. I am unable to appropriate sideboard as the system is unable to recognize that I am submitting a valid deck.

There seems to be a bug with companions and sideboards. Was playing draft earlier today with Lutri. After sideboarding and clicking "done" it would proceed to the game, but my deck was unchanged.
