Hello, while I'm aware Tier 3 hammer is required to break them, we currently cannot acquire the upgrade. From what I can see, they don't despawn either. Can you please let them despawn or give us a way to dispose of them? I currently have a large shell sitting inside of a blueprint I can't finish because of it. It wasn't inside my base at first but a dang ladybug pushed it in. I tried pushing it myself and even using a buggy. It won't budge!
