Hello, I have just received my basic bow frame from Ada-1, and acquired a weapon core. However when I started killing Vex in Nessus in order to acquire the Unstable Radiolaria, they where not being dropped for some reason. And now I am stuck at 0/25 and I can't seem to find any advice anywhere and deleting the frame from what I've read is counter productive since Ada-1 will not return the frame. How can I fix this so that I can get my bow. [spoiler]Moderator edit: This thread has been updated with tags that are more appropriate.
