[Therion] using XVI as background image

I'm using an XVI image as the background for a simple scrap. Loading the XVI works perfectly, defining stations using it works perfectly. However, once I close the .th2 file and reopen it, the XVI is offset relative to the scrap. I only generate the XVI image once at the very beginning. I don't regenerate it every time I compile. I've attached a screenshot which should be illustrative. -JP
