Don't worry about it, I watched my p.regalis burrow like lightning into hard packed substrate to avoid being rehomed into a new enclosure, leaving no trace of his existence. I had to dig him out and I was amazed at what he had just done. He probably burrowed and did a good job of covering his tracks.
I had an OBT sling escape from me a few months ago. I hate some of my neighbors so I told them to BOLO for an extremely aggressive, hungry, and furious killer tarantula.
