Looks like one of my Enhanced Crystal Collectors isn't registering. In the pictures, I have 2 of them setup, but the one isn't registering anymore. I've tried to rebuild it, and restarted Minecraft to see if that would work, but nothing seems to. Not sure what I'm missing.

Here are images, the 2 structures are setup the same: https://imgur.com/a/3xTnrlL

Just a follow up: I had an idea to just fill in all the space around the structure with blocks, and then break them all to see if minecraft thought something was there. This seemed to work. There were no other blocks around it, but I think MC was freaking out or something.
