I'm playing on my account that I just updated through cross-save from my playstation account. I haven't played in a long time on that account (last update I really played was up to the end of Mercury campaign with Osiris). For some reason I can't infuse my weapons or armor at all. It shows that I should be able to, I have an upgrade module, and my gear is not locked. It let's me select the weapon/armor to infuse into my old/good armor, but it just flashes red and doesn't let me go through with it. I don't know what the issue is exactly, but it isn't even working on new gear that I got.
