Similar to others, had an issue with attempting to spawn “Lepidoralia the Resplendent,” but also noticed that the cave had a visual glitch as well. While bouncing through the cavern attempting to catch the Reveling Shimmerwings, I kept getting a view of the surrounding environment outside the cave in a slightly blue haze.
I was able to find a spot at 33.82, 87.27 where I could screenshot the image issue. This was in the upper area of the cave, where Lepidoralia is supposed to spawn. Link: hxxps://postimg.cc/gallery/fyzX64b
From the same spot, you could also see another image poking through the side of the cave wall that shouldn’t have been there. Link:

Hope this helps. (Replace the xx in the links with tt)
