It just got beat up during shipping and is separating from it's base a little. Give it a few days to recover. They are very hardy. I have only had one leather really get to the point that it was either frag, or death, but you will know if it gets to that point. The bottom area will become dark/black like rotting flesh. If it gets to that point, pull it out, trim off all of the dead flesh, and reattach the remaining part to a fresh rock or something.
