I've been playing around in the new update, having a wonderful time btw, and I've gotten to the point where I need Iron ore. I'm currently in the Sylvan's Cradle portion of the game, and have scoured every inch of the map including the caves to try and find iron, and I am having no luck at all. I even built the portal that puck told me to build, and went to a swamp biome to see if I could find anything there, but no luck there either. What I would love to see is either some device or spell that we could get to be able to see where ores are. Not sure how easy or hard it would be to implement, but it would be a great quality of life improvement.
