So far I'm running a ton of mods perfectly, but Dual Sheath is the one that I can't get. Of course, it's one of the better ones as well.

If I activate it in game, it says to run the SkyProc Patch. I understand this means I go to the Data Folder, open the SkyProc Patches folder and run the java script "Dual Sheath Redux Patch"

I hit "patch" in the upper right corner and it gets to 46% before stopping with a message popping up saying:

skyproc.exceptions.MissingMaster:

JSwordsDistributionBalancePlugin.esp has some missing masters:

-JSwords.esm

I assume this is from the JaySuS Swords mod? I have the Distribution Balance plugin, and I was 90% sure I downloaded and activated the mod itself. Is this telling me I need to re-download the master file for JaySus Swords, put it ahead of the Balance Plugin in the load order, activate it, and try the Dual Sheath Redux Patch again?

[Edit] - Just browsed over some of JaySuS Swords images at the Nexus. I stopped at Azurebrand, a unique sword apparently added by this mod. I strongly recall the last time I played Skyrim a couple days ago, the point I stopped at was finding Azura's Star, with the unique sword Azurebrand next to it. So I either have this mod running, or another mod that added Azurebrand to the Daedric Quest.

Do you have JSwords.esm active in your load order?

I do. It is after Skyrim, all of Skyrim's DLC additions, their unofficial patches, Falskaar, and Climates of Tamriel.

So it's pretty early in the load order.
