The photo says it all. For some reason I detect mining nodes in the sky, or... wherever they are. So far, this has only happened once. I cannot find the nodes, probably because they actually aren't there. I have no freaking idea why or how this happened.
Photos coming in a minute.
Updated with photo.

Edit: Okay, so I found out that these are in the caves, please map out the cave entrance a bit better, it was extremely confusing. :Z
