I found error in manual reward distribution mechanism, and now I need to redistribute donated funds again. Don't worry, you shouldn't do anything.

Preamble

One of my users, Lasgermab, found, that he received too small amount from distribution. He asked me why. And I started to investigate.

What gone wrong

I checked my manual reward sender and found that it uses old project statuses mechanism.
Here is distribution of second donation fund:

Most of funds were received by VGTU contributors, despite that project shouldn't be rewarded (not in superblock).

Fix

Fix requires only one change in billing.php:
Before:

$enabled_projects_array=db_query_to_array("SELECT `uid`,`name` FROM `projects`
WHERE `status` IN ('enabled','auto enabled','stats only') AND `present_in_superblock`=1");

After:

$enabled_projects_array=db_query_to_array("SELECT `uid`,`name` FROM `projects`
WHERE `status` IN ('enabled','auto enabled','stats only')");

After fix

Now rewards distributed correctly:
