Although the Fairelands are fading back into the mists, there is one sim holding onto the grid for just a little bit longer: The Palace of Tears sim stays in existence, open and alive for a week still, all the way to May 18th.
This means that you can finish the second part of the hunt at your own leisure within the Palace. The hunt HUD vendors will sell HUDs that cover only this second part of the hunt, since the first part will become impossible to work on once the rest of the Fairelands are gone. Obviously the HUDs you purchased during the Faire will continue to work as well.
Come solve the puzzles, admire the art and enjoy the last Faireland of year 2014 for just a little bit longer!
