So my guild was doing H.Ruby Sanctum 10 this evening and we reached Phase 3. We pushed him into spawning the portals a little preemptively during the Shadow Cutters, but didn't think anything of it aside from knowing he'd gain a percent or two health. Our fire world team went through the portals and it all was looking good...and then both of the healers (we're trying a 4-healing thing just to cut down on the bad luck during p3) couldn't heal anybody. They clicked on the portal, their screen flickered, and then they were in the Shadow world again but not; they couldn't target or heal anybody, obviously leading to a prompt wipe as the fire side tank died.
I was just wondering if anybody's ever had this happen to them or heard of it? And if so, any way to ensure it doesn't happen again? Thanks.
