If it helps bring anyone else ease of mind, here's mine that has the lab in its summary. Definitive proof that you are in fact doing the right thing and that unfortunately luck just isn't on your side! Fwiw, it took about... 50 reloads on my end? Counting timed ones, my 10 free reloads, and the actual item reloads. So yeah it's all luck-based! Hope y'all find 'em soon!
