The scorers do not import from MyCricket when importing a match. It also has issues when there are more than two umpires listed. (eg when an umpire is listed for day two only, etc)
OK Do you mind doing this:
Create a new suggestion about the scorers. Include a MyCricket MatchID where there is a Scorer listed. This will get priority.
Create a new system issue with an example MatchID where there a more than 2 umpires listed and it is not importing as you would expect.
