In my friends world,we've made it 100+ but have run into a big issue recently. One of the natural spawned pillars in the Ancient Archives had fully blocked the entrance of the Ancient Archives. This practically makes progression impossible without a lazy explorer. Is it possible to fix or change this natural blockade or change where they can spawn so players may not have to deal with the same issue?
Open up a world and find the Lunar Grotto and have natural generation lock the area to you.
