Hi, there is a bug with the misson board.
You can accept all the quests together, but if you have gathered all the material and mark one quests to completed, all the material for all the quests disappear from your inventory. The quest is still there for a bit but if you close and reopened the quest window, the quests have disappeared. You can't move forward with the story and you are forced to reload and gather 2 times the resources or complete 1 quest at time.
