[URGENT] Completely invisible teamates!!

I have not yet attempted to replicate the bug, but will do that in the next couple matches.

heres what happened. I was playing Garen top in a ranked match up. My 1 year old son saw the nice shiny power button on my PC and pressed it in the middle of the game. I subsequently cancelled the shutdown but only after the game had exited. I immediately re-opened LoL and reconnected. Upon my return everyone on my team was completely invisible. No fog of war "bubbles" following them, even when the enemy team attacked I could not see who they were targeting. I saw Leona's ult but I couldn't see other's but they may not have been near me. I had them ping on the map and I could see the pings but no icons on the minimap. I didn't look to see if I could see their wards.

Due to the serious impact this can have on ranked stats I am going to attempt to duplicate it in an ARAM match and if I cannot duplicate it I will try a normal, and lastly in ranked. I will post anything I find below. In case it matters how long the match was, I can only guess at the time it happened, somewhere between the 28:00 and 30:00 mark. I don't record my matches but linked the game in case there is a way to see what happened.

Anyone that happens to read this and is willing to try it out please post your findings here so we can get this worked on.
