Item List Creation Issue

Not so much a bug rather than an issue I had that would be nice to have fixed. For item set creations, they don't seem to save and import into the game properly if you have LoL installed on any other drive than C. I have a secondary larger drive I use for gaming and when I had LoL installed on it I could not access saved item sets in the shop. They would save in my profile, but in game would not load up the lists. I re-installed and let it default install and that fixed the problem. So if that's true and you can't have LoL installed on a separate drive, it would be nice to have fixed.
