[Lazortag]

Very rarely when two people zone somewhere at the same time, one becomes invisible to the other, even though the other can see them/cast on them/etc. This happened once when I was assisting someone on a CR, we zoned at the same time and she was invisible to me on the other side, so someone was able to attack her but my buffs wouldn't land on her. I could even see someone attack her except it looked like the person was attacking thin air if I remember correctly.
