Description

There is a bug in the SortedPreferrentialArray in which after the Recyclye bin has been filled, and a spot in the bin is requested that is larger than the largest element, the last element in the array is returned. If the last recycle bin spot is not actually the last element in the data file, the element after the recycle bin element will be partially overwritten with the new data. That element will no longer be valid, which will eventually cause the entire cache to be reset.
