So my league stopped working, so i had to manually repair and readd the UserKernel.app file which restored my game. Problem is, is that now i lost all my item sets which took me a long time to make, So if anyone knows a way I can bring back my item sets please tell me. And for those of you who say go to releases I only have one version under it instead of the supposed 2 or more.
P.S. I have a Mac
