So when I've been testing my load order, I discovered an incompatibility between the mods "Daedric Shrines - All in One" and "The Secrets of Arc Cyrae". The problem was that the Shrine of Sanguine would be placed at the exact same location as the player home from Arc Cyrae, resulting in the shrine being "devoured" by the player home. I fixed that by moving the Shrine of Sanguine not that far away from that location. Furthermore I disabled the trees added to the shrine so that they won't clip with the player home.

Important: This patch does not include neither the assets of "Daedric Shrines - All in One" nor "The Secrets of Arc Cyrae" and therefore requires both mods to work properly. You will also need the Wintersun Patch from "Daedric Shrines - All in One" if you have Wintersun and want the shrine to give you blessings.
