Just started up again after several years, on medium setting, but I noticed that the aliens had a different tech increase than before. They took a lot longer to get better UFOes. Im in week 10 now, and The biggest UFO I have seen is 5 and 6. ANnyone else seen this?

Alien Tech increases based on your weekly score. Have you had a lot of damage to the coty or many more casualties than normal, or even just less tactical battles that you usually fight?
