These nodes have some sort of geometry issue. Some you have to stand on top, some on the side, some you have to back up and back in to find a "sweet spot". If you stand on top of the nodes it's usually no issues. However, most often than not, you get can't see the node to harvest it. Can these nodes be adjusted so they can all be harvested like regular nodes?
Not all of them are that way. I'd guess and obviously a wild guess that many/most are that way. Very few I can just run up and harvest without standing on top. How can I help with narrowing down the nodes? I can try and submit a /bug with specific ones, I'd venture that wouldn't be super helpful with how many nodes there are?
If its not all of them then its like them ground causing the issue. I will do a pow wow with the art folks and see if we can track it down.
