To begin with, I found the cave shortly before the server crash last night. I placed my HF at the entrance as soon as I was able to. I was in the cave getting mats out of containers and waiting for one last curio to pop. I walked outside and suddenly there is a claim on top of it.
Oh, and by the way we did a bit more than just HF spam.
EDIT: And I love how you admit to grabbing something that others are working on and then cry to the forums when we enact revenge.
