Zero MR Bug (PBE Visual?)

While in an ARAM on the PBE i had a bugsplat that crashed the game. I was able to just click "reconnect" and was brought back to game. I noticed that i had "0" MR displayed. When i clicked my champion profile it also said "0" Magic Resist. I did forget to screenshot that as well.

I'm not sure if this was just a visual thing, or i in fact had 0 MR. Katarina was the only AP on the other team and in the time it took me to cast my ult she 100-0'd me (outplayed...?)...and i had 2.5k hp. So this makes me lean towards me actually having 0 MR.

Notes: I had the items built in the picture attached Was running all scaling AP runes 21-0-9 Masteries This happened AFTER a pretty random bugsplat (that surprisingly didn't get me killed)
