Good point, I'd forgotten. So either Barrow come up and their League drops by a team, or Barrow are denied promotion. As I was saying, they all need to be void, it's the fairest way.
Reports from Germany that the league is starting again, but at least one state has ruled that football can't restart yet - so the teams in question (Hallescher and others in Saxony-Anhalt) in League 3 are under threat of being thrown out of the league for complying with government instructions.
