Hey!
Thank you for detailed explanation. As you can read in my previous post, It is all setup pretty well:
Redrake_s_IWD_Fixpack needs AB (component 3)." (Auril's Bane Grog's IWD Fixes) and since "Auril's Bane Grog's IWD Fixes" does the same as iwdfixpack" i've changed the requirements for you mod to "Redrake_s_IWD_Fixpack needs IWD Fixpack."
Now, I've added another condition that Item Upgrade is not compatible with Redrake Item Fixes: https://bitbucket.org/BigWorldSetup/bigworldsetup/commits/0135d09a44c35d82bd3396e339d98c2c760413db
Ideally, all those various fixes from AD, Grog's, Redrake Fixpack should be combined to one and make compatible with Item Upgrade but you can't have everything But the most important part is a stability and avoid conflicts which I believe, BWS install order provides. Thanks again for you mods and work.
P.S. Almateria recently released her "ALMATERIA'S IWD2 FIXPACK 3" ...
