I'm out of upgrade modules and it seems like I can't get anymore. I've used the different modularity mods on my ghost in all three different modes available (strikes,crucible,gambit) and i've specifically won multiple games in crucible and gambit and none have dropped. I can't buy any from the gunsmith because here I was thinking that the destination materials from vaulted locations would only be good for getting glimmer from spider, but no apparently I need them to get something that wasn't taken out? This week gunsmith is asking for phaseglass needles and simulation seeds, both of which I have none of because, like I said, I've already used them all up on either previous upgrade mods or glimmer from spider. The change would just be to take out the requirements of no longer accessible materials from currently necessary items like upgrade mods. If you want to keep them in that's fine, but make an option for only the currently accessible destination materials.
