Nullable object must have a value

If you are attempting to change the Handicap Limit Type on the Handicaps step of the competition wizard and when you click on Continue you receive the following message:

The cause of this issue is a player is booked in who had a handicap at the time of booking but no longer does, if you are unable to find which player this is please raise a support request with us and we will be able to identify this and inform you of the players name.

We do have work planned to stop this issue occurring and this article will be removed once the fix has been applied.
