Did some weapons get removed from the fabricator?

I play solo Horde a couple times a week to do TOD challenges. The orher day I noticed Lizzie couldnt buy a dropshot from the fabricator. Even though its in her loadout. Every now and then i would dtop the dropshot for an overkill or Boomshot, and I am 90% certain I could just go buy another one a few rounds later…Am I remembering things incorrectly, or did TC remove it? Thanks
