Hey Saltamontes, same thing happened on a private hive I play on (which was only set up a few days ago). It was near Novy Lug, pretty beat up. Spent a few hours repairing it before the admin learnt I had it and despawned it. He assumed a hacker had spawned it in, although a friend said he saw it a day beforehand which meant it had survived >2 server restarts.
