What does this pull request do?

This NPC should appear between 18 and 6 on full moon. However, the condition is wrong, so that it never appears. This PR corrects the issue. https://www.bg-wiki.com/ffxi/The_Stars_of_Ifrit

Steps to test these changes

During full moon, the NPC will appear between 18 and 6.
