I'm at year 6 of my campaign, I've made 25 suits of annihilator armor, and I'm currently making Tesla cannons for my 4 SABREs so that I can shoot down a Silver Tower so that I can get the Star God Coordinator that I need to be able to go to Cydonia. As it's currently just a matter of time until another one of them shows up again, I'll have to wait until they arrive. But in the mean time, I'm having some issues with certain crafting materials- I can't seem to find enough laser lenses, focusing crystals, focus circuitry, or jewels to make all the stuff I want to use on Cydonia.
As I'm so late into the campaign, I'm encountering problems with finding any laser weapons to disassemble, as most of the enemy UFO spawns are Star Gods, and the other major factions - like the Church and the Academy - only rarely spawn, at most once a month, if at all. And even when they do spawn, it seems that I can only get about 10 focusing crystals and laser lenses per mission, you need hundreds of them to be able to make all the things that you need in a campaign. I know that you can get gemstones from mansion invasions, but I didn't know that until recently, and it seems that mansion robberies have stopped spawning altogether. Is there any way that I can get the materials that I need, or am I just screwed?
