UPDATE (Wed 12 Oct): The issue has been fixed and data + accounts have been updated.
UPDATE (Sun 9 Oct): The same thing happened again: account updates stopped working on Saturday 8 October at about 4pm UTC, due to CB's affiliate postbacks malfunctioning. Unfortunately these things are completely out of my hand, all I can do is report the issue to CB and wait patiently for them to solve it...
UPDATE (Thu 29 Sep): The missing data between September 16 at 2:20 UTC and September 19 at 17:15 UTC has been added and any account upgrades have been processed. Users who's account was upgraded due to this fix, have been notified.
UPDATE: Account updates have been restored to working order on September 19 at 17:15 UTC. The missing data and any account updates from inbetween these dates will be amended soon.
Just like back in February, the automatic account updates stopped working on September 16 at 2:20 UTC, due to an issue with CB's affiliate reporting. The problem has been reported and hopefully will be fixed swifly...
