Trial of Chaos Soul Core Bug

In the Act 3 Trial of Chaos, the "find the vaal soul cores" room is bugged. There were no soul cores in the entire room, and after all the mobs died there was nothing to do.

I tried the Trial again and the same bug happened. After logging out, I created a new instance and tried once more. This time, the room had a new layout and the soul cores spawned.

Same bug for me just now. Sadly, after relogging the trial was gone.

Ran into this once after the 0.1.0d patch, unless this got fixed on server-side later (was able to get the cores in another attempt)

edit: found the hiding spot, didn't know i could go back up before the trial was done.
