Player had the pipe in a nomad book, which worked fine deploying over and over, however he got hit with a bad explosion, and picked up what was left of the nomad book(mobile base) and when he was in the overworld and deployed it, it crashed the server.

Thanks for reporting! It should be fixed in the next version, of which you will be able to download a nightly build here in about 10 minutes... Please re-open if that doesn't fix it
