I finally unlocked Oden Geiger, rolled up with lots of materials planning to upgrade two mods per suit, and once I added NV he would not add Battery. This is a G5 Mav suit with only one mod before those, so there are 3 free mod slots. I tried to add them in succession without exiting and I noticed it was trying to apply Batt over top of NV which of course failed. He still said something affirmative. After exiting the mod screen and going back, he would not add Batt to the suit when the next slot down was highlighted. He still speaks as if he is making the mod but it does not add and the materials are not taken. I have relogged to desktop, switched suits in ship, and still he will not apply the mod to the suit. I have enough materials of course. Is this a bug or intended? Thank you!
