It still is progress in a way, even if things get wiped clean. Ranked Magic was likely introduced by previous Players. This was World changing. Non-NW native monsters were likely introduced since many monsters share abilities and descriptions between the NW and Yggdrasil. This is also World changing as it would require a fundamental shift in society. We don't currently know any NW only species of monster, with the exceptions of Hamsuke, the Giant of the East, the Dragon Lords, and the Tree. (And of those the Giant may have just been a mutant like Roro, which wasn't noted to happen in Yggdrasil, and the Tree may have been another introduced entity... from where we're not really sure, other than the fact that Ainz had never run into it or something like it before.) All other monsters encountered by Nazarick so far has been familiar to them with those exceptions. This small little quirk already sets me on edge since that's way too many similarities not to have some kind of common link. I also don't believe there would be much of anything left in Yggdrasil that Ainz hadn't at least read about if not seen... exploring things with the other AOG members was implied to be a favorite of his after all.
