Steps:
We were fighting the Curator and I noticed I was getting hit by Broken Glass and mine explosions even though I was nowhere near them. I don't think it was an issue of lag, as A) I was not experiencing any and I was healing, and B) I wasn't running through the glowing tiles or mine squares, they were hitting me from afar.
