Oversight mod fixes the bug with the Ranger/Cleric being unable to get the Cleric stronghold.
Forgot about the Ring of Holiness (the Cleric stronghold was the second stronghold I did, many many moons ago). Actually, I can truthfully say that I really didn't like the Ranger stronghold. I just felt it was too short. Cleric stronghold is longer, and takes more thought overall (having to advise others, while keeping with the faith that you have chosen; I love the Talos version!). Some people don't like the Cleric one because it is all talking and little to no fighting, but I love the fact that the "best" options change based on which temple you choose (i.e. your alignment).
