Fairly small issue, but the Quest Iesnum: Ore of the Otherworld in the Occultism Tree uses Raw Iesnum as it's trigger condition. With any other ore this would work but Iesnum is acquired as a full block due to the special equipment needed to acquire it. Raw Iesnum can only be gotten through using Productive Bees, but this does mean that the quest can currently be completed. When you get a chance it should be swapped to Iesnum Ore.

Will be fixed in a future update! Thanks for letting me know :D
