What a screw up this is.
You Funcom guys really messed this up.
Get rid of all the stupid rays and just make the quest better.
Because of all the various idiots clicking the crystals while someone else is attempting to solve the puzzle step, the quest gets bugged out, reset and causes all kinds of angst.
Remove all the rays, leave the crystals so when you click one, ONE ray appears and goes through the cycles of the direction the clicker wants the ray to go. Then they move to the next xystal and so on to the finish of this Tier.
Because of all the rays all over at multiple times, all kinds of players click this and that despite some other player might be almost done, only to have to start all over because some clown just reset the starter crystal.
The quest is not that important in this part of the tiers to make this part such a pain.
