ANY pack with ANY set of duplicated mods AFTER upgrade/downgrade.
Known Fix:
This is a Launcher bug (not pack specific).
You must delete BOTH the install location's mods folder, AND delete the entire Direwolf20 1.6.4 (similar name) ftblauncher cache location (the exact spot varies from platform to platform).
You might also need to Force Update after this to get a working install (I was /really/ frustrated by the time I reached this point so I don't remember if a final Force Update is required).
I have 2 issues to report. One is both a launcher error and a Direwolf Mod Pack error, and one is a saving error.
Mod Pack: Direwolf20
Mod & Version: Tinkers' Contruct 1.5.2.1 and 1.5, and Thaumic Tinkerer 2-38 and 2-44

Whats the bug? The First, is that when I updated to 1.0.2, I consistently get a mod duplicate error. I remove the mod, but it returns after I launch the pack (It is on my desktop during this, so I know it is moving it). Second, When I edit my Ars Magica UI, It doesn't save. I don't know if this is an Ars Magica Bug or an FTB Bug, as I haven't tested it by itself.
Can it be repeated? Every time I launch
Known Fix:
If it helps I am on Java 7, OS X 10.9.
