Ssithy failed to spawn

[maudlin27]

I did a ssith run earlier today with a moderate sized group. I'd checked before hand to make sure the portal hadn't been opened and ssithy was still alive before starting it. We made our way to the bridge, and eventually got to the end (after quite a bit of dying!). However, when we got to the end, and used the portal key, we arrived to find Ssithys guardians all there, but no Ssithy. We killed here bodyguards and ran round the area to check, but Ssithy failed to spawn. I then logged in another char of mine who ran back over the bridge and used the portal, but that also failed to do anything. The PCScry device still showed Ssithy as being alive as well.
If wanted I've got a screenshot of the incident, with us standing in a nice neat line where Ssithy should be, along with the PCScry saying ssithy was alive, if needed, and I think some of my partymembers should have had as well. It was very disapointing as it was extremaly tough for us to get that far, and was a shame to miss out on the tag+loot. We were also unable to use our chars on that server until the next reset, as there was no portal for us to return (in my case it was 2 chars as I'd logged the other one in to get there as well). We checked all the servers, but there was no DM we could find to help us either.

Is there any way either to ensure ssithy doesn't vanish/will spawn, and/or to make sure the PCScry device will accurately say if Ssithy is there or not? I couldn't help but feel other people might organise a ssith run seeing ssithy still alive (and no-one on ssithy run), only to get there and find ssithy wouldn't have spawned.

Someone in your party despawned it.

Is there any chance of making the PCScry correctly display this then, and say that Ssithy is dead if its been despawned, as having it say Ssithy is alive when Ssithy is no longer there is quite a bit confusing, and could lead to more aborted runs at the end.

All it takes is for one person to enter the portal then come back to the temple and pfft no Ssithy. Something else you have to watch out for (in a small party anyway) is all party members ring resting at the same time or its pfft no Ssithy, I speak from bitter experience on this one!
