After making my final pick in a draft, I often see a "Network Error" popup message: "Unable to finish draft. Please try again later." This has been happening lately with the Arena Cube Draft, and my wife has experienced it many times as well.

There is no problem with the network connection, and this happens consistently after the last pick in the draft, so it's clearly a problem with the software and not the network.

What's most annoying is that I've been putting cards in my sideboard and building the deck during the draft, but when this error occurs it forgets all the selections I made and instead puts all the cards back in the main deck for me to have to sift through and rebuild the deck again.
