Prizes were pending a minimum participation of 5 people who submit. The prizes were being adjusted several times because we have a limited budget for the jam and that information was not exactly clear to the organizer at the time it was written. Probably should have been left TBD until all the information was clarified. The final adjustment came when of the 20 something folk who joined, too few had submitted, less than five people. Another reason for a smaller prize pool is that in the case that we hold more jams later this year, we still have budget to offer for prizes.
Regarding the date adjustments, some folks had run into issues submitting, making their build, etc. at the last hour and so a grace period was allowed of an additional day since the complaints were read the very next day rather than on submission close. Because it was strange that so few people had submitted considering the amount of folks who had joined, it made sense to open it back up in case it was a more widespread problem than originally thought.
This event is volunteer run, and since the few folks who run this event may be caught up in other things throughout the day, we can't be on this all the time, so some issues slip through the cracks until we log back in and take a look. Apologies for the issues and we will strive to do better.
