Spyglass isn't correctly showing location of fae glyphs
After completing the sewers i returned to the ones i could see before and still cant see them, attached F2 screenshot for location of the POI
After entering the sewers with my new transfered character i can see the glyphs with the spyglass, dont know if is only some of them, need more test
Still works for music pillars and the one about standing in the circle till the glyph turns blue but not for the one the OP talks about
