There was an issue with bugs. The whole system got re-worked. One of the indications of the problems that were cropping up was a massive increase in spawn rate of the insects that got removed/sold. They were just... everywhere. This caused their value to be a problem (some one catching thousands of mantis, for instance, might give them a huge boost of income). Subsequently the rains came and the bugs with issues were 'sold'... resetting the system.
