I'm not sure why the spin exploit even works because you'd think it would be laughably easy to make it so an enemy's AI script progresses regardless of whether it's actually moving/auto-attacking (It seems like they need to be doing one or the other).

But yeah. After failing miserably at a solo GNB attempt on floor 82 due to awful RNG I find this development particularly annoying. Sometimes the game just decides it doesn't want you to have a successful run.
