Mastery Bug

I was in Champ Select and making my masteries for Zyra. After the page was done, I clicked save and received the generic "Error: An unexpected error has occurred...". I thought it was weird, but when hovering over my masteries and double-checking that they were correct, I assume it was just some weird error that I could ignore. When I began loading into game I noticed that I had no mastery icon (the one you get for having 18 points in one section). I checked LOLNexxus and confirmed that I had no masteries. Upon coming out of the game I checked my other mastery pages. I now get the error every time I go to any mastery page. I am scared that it is bugged to the point where I can no longer use masteries.
