The problem here I think for the unlimited play 9 holes for wks 20 to 22 (it will be a problem this week too) is that there is no prize fund for any tier listed, and thus when the batch job runs to allocate the prizes, nothing is given because there is nothing to give.
e.g. 18% of 0 is 0 (when I went to school).
So I would say that the prize allocation run for wks 20 and 21 have already taken place, and the code finished successfully, but because there wasn't a prize fund, noone got any credits.
If someone wants to send this on to members@worldgolftour.com, as I won't have access until tomorrow
