Notices & Updates

Sort by Generation
October 19th, 2021, 12:13 AM
The old sort by origin option has been changed into sort by generation. All instances of origin sorting within Collection and Folder sorting have been replaced by generation sorting. Sort by generation is ascending, starting from the lowest generation number (1, which is any Wild Caught creature) to the highest (2 and above, which is any Captive Bred creature).
