[CRASH/FREEZING] Butcher's Bridge

I am experiencing game freezes only in this game mode. I did not play the previous time Butcher's Bridge came out so I can't know for sure if there's a correlation. Visually, the entire game would freeze, though sounds will come through. It would then flicker to a solid tannish-brown color, to black, then recover to normal from 1 to 5 seconds at a time. This issue occurs estimating on average once per ARAM game, iirc the most I've seen it occur was three times in one game. I've experienced this while dead, in a team fight, buying, only moving, etc. so I can't seem to find a pattern between any of the occurrences. Again, I do not experience this on Rift so at least it's isolated to this mode. I will edit with additional information if I can figure out a correlation.
