As you may see, your .th2 file include only those three stations (and sketch). Probably it is bug in Therion that it not allows to hide stations from the final output. I may imagine the reason - MetaPost works with one scrap in time to interpret and draw that particular scrap. When it has nothing in scrap it will produce error. Martin
