Hi there,
What section of the CK points to the Loading Screen messages? The http://www.uesp.net/wiki/Oblivion:Loading_Screens provides a good list, but is it absolutely complete?
Curious to know, as there appeared a message to the effect that "Going for a Dip in Lava Can Increase (permanent) Fire Resistance."
There appears to be no mods that provide such messages, or at least there haven't been any loaded in this recent re-installation.
The Breton custom character went for the obligatory dip in hot stuff (as you do), but player.getav ResistFire before and after netted 0.00.
So the mysterious message still has this player in a lather about the lava.
