I received the Black Iron Ore and returned to Etceter to give it to Avitas. My inventory pops up for a second but goes to conversation mode immediately. I can't give him the Ore, but he does tell me to get to Xenos. The quests are still in my journal. I went to Xenos but can't get to the next quest line because it says I still need to talk to Avitas to get put in the lottery for the pilgramage (I assume that's what I need to do).
