Ok. It says to use the Duty Finder to undertake the guildhest "Hero on the Halfshell" But the thing is, it is not listed under Guildhest in my Duty Finder. It's weird cause when I click on the blue letters under Hest of the Best, a map pops up displaying a red circle at around x-18, y-23 in Central Thanalan.

Hest of the Best and Hero on the Halfshell appear to be two totally different quests that has some how been merged and glitched. Hero on the Halfshell is a Lv. 15 Guildhest and Hest of the Best is a Lv. 50 Main Scenario Quest quest. @@
