[Client] Importing a PBE ItemSet breaks Live client ItemSet

First let me say yes I know how stupid am I to try using PBE stuff on the Live version but I'm lazy and was hoping that missing information defaulted to nothing in those parts instead of breaking something. Wanted to get my Kai'Sa items moved quicker.

1: Export an ItemSet with anything that does not currently exist on the Live server. Example (Kai'Sa as the selected champion) 2: Import that ItemSet into your Live client 3: Should result in a blank and nearly unusable item set screen on the Live client. Attempts to view your itemsets show that none exist and create new brings up a blank page

EDIT: While typing this I tried a few things from restarting the client to deleting the itemset.json file but it would appear it's attached to my profile and is replaced when logging back in

I found a fix right before hitting post. At the bottom if you select a champion and try to create a new item set that way instead of using the create/import options in the middle brings you to the full working item set page. From there I had to go over to the PBE ItemSet that I had imported and delete it. Now the ItemSet function works properly

I feel silly for even attempting this in the first place. [zombie-brand-facepalm]
