New players stuck in campaign

There have been several posts on Reddit and Discord in the past weeks/months from new players who get stuck in the opening campaign after they delete Black Widow to make place for a different character. Since BW is required in one of the campaign nodes and they can’t acquire new characters or tokens yet, it basically perma-locks them out of the game.

Several experienced players other than me have tried to flag this to the Devs on both platforms so far without any response. Hoping this post might finally help. Seems like a fairly serious bug and I’m surprised it hasn’t been fixed, or at the very least acknowledged yet.
