I had this quest, called " Digging Sand", the npc Afuaru told me to go somewhere in desert, at a pinned location, where I found a flag. Not knowing I had to interact with it, I started digging around it, and interacted right after. I didn't know I could've acquired more shovels from any material npc, so I thought I'd just reaccept the quest and get the shovels again from Afuaru. When I hover the mouse over the quest, it tells me I have to complete the quest before, and then the one before and so on, till the very first one in the quest line. I can't reaccept it.
