I ran across this bug recently: I have a multiple stronghold mod. When I went to the Temple area for the first time, Gaal did his rousing speech as per usual but no priest came to talk to me. My character's alignment is good so I was expecting the Lathander representative to approach me but he was nowhere to be found. I tried looking for the default Helm representative but he was nowhere to be seen either. So then I went on Google and began a quest for this bug fix.
I tried to CreateCreature for the various priests but they were unresponsive. CreateCreature was a little problematic also, because I wasn't sure what the names for all the priests were. I also tried to use the EE Keeper with marginal success.
I finally ran across a post in a PocketPlane forum that was the exact fix I needed. It uses the CLUAConsole CreateCreature but with a little twist: you must add a "bh" in front of their creature title.
High Mornmaster Arval - "bharval" for good characters High Watcher Oisig - "bhoisig" for neutral characters (or default with no mods and you're not a priest of Helm) Stormherald Nallabir - "bhnalla" for evil characters
So I am posting this in case anyone else might need it.
