Phased after being disconnected

Doing elites in RR as a level 32 (pocket) priest. I suddenly disconnected on second floo of hall. I was able to immediately log back in, but was phased. I was alone in a room full of elites. Died just outside the hall. Questiin, why was I phaaed when still grouped. Rest of my group hearrhed out thankfully.

Layers is the answer to this. Blame those wanting mega-servers.
