• Fixed: Artifacts would incorrectly try to be created in layers that have no blocks, such as in the case of adjusting your Starting Layer, which would make finding the artifacts needlessly difficult.
• Fixed: Fireflies can now spawn in all layers.

Please let me know in the Steam Discussion Boards if you continue to have situations where artifacts are very very difficult to find. Please include which layer you're starting on and which artifacts are missing. I believe the bug has been fixed, but if not, I'll need those extra details. Thank you.
