Your hack of the Junction.system seems to work. Even missions going to it work. I had a strange phenomenon at the oceanic planet there; not sure whether this has anything to do with your hack, but just in case: I took a cargo mission to Troy, but I couldn't buy anything else at the commodities. I had 45 free cargo, there were items to buy, but nothing happened when I clicked on Buy. And I just verified that Haven still doesn't exist; supposed to be able to jump to it from J900. Should I send you my J900 file?
