The fucked up thing is that I didn't originally start this run going for naneinf, but since I stumbled into it I'm like, "fuck it, we ball". I was trying to finish out my joker collection, just needed Eris unlocked for the Astronomer joker, which I saw in the shop literally just before I hit "next round". So not only did I fail the naneinf, I failed at completing my joker collection too.
I got Blueprint, you can see it in the screenshot, but yeah I didn't get it until late in the run, so I never got to dupe it. And yeah, I never saw Mime.
Oops sorry, that was my bad! Thanks for the heads up, and too bad about the run. What a buzzkill that must've been.
Yeah, but life goes on, and I did find Astronomer in the next run, so I got one goal accomplished!
