Seriously, why not make the crafting hall on the teleport spell send us to the one in house Cannith instead of the other one? This would make since with the rest of the teleport locations as they send you to a specific location inside of the location that you are heading too (like the Magic Shop in house J). This would also give us a way to teleport to house Cannith without you all actually make a completely new icon, expanding the list, etc.
