FH Query - Pyroxene

In the plug-in Frozen Heart, I've been offered a couple of missions to Pyroxene in the Theemim system. Trouble is, there's no such place - there are no stöbs in Theemim at all. The first time I got such a mission was from Tejat, so I dismissed it as just another example of Tejatian humour. However, I've since seen missions to Pyroxene available from other planets. I looked in ResEdit and there is indeed a stöb named Pyroxene in Theemim, but I don't know enough about visbits to figure out what I need to do to make it show up. Any suggestions?

Question authority. That's an order.

This same thing happened to me while playing a Star Wars plug for EVO...
