Guild Wars 2

-may contain minor spoilers-

I stumbled into this puzzle about 1.5 hours ago. I figured it out all on my own and collected the power sources that are required for the chest at the end. I collected 7 sources (6 are required for the chest). I approached the chest and inserted a power supply into the first node. Instead of it placing a single power source into the node (as it should) it used up all 7 at once. So I no longer have the required number to complete the puzzle and claim my prize. I will not return to this puzzle until I see patch notes that it is fixed.

-Edit-

It looks like it stuck them somewhere else.. Into the nodes at the chests I was not trying to unlock. I don’t know if this is by design or not. If this resets daily then it would still be impossible to unlock the main chest… As they are not enough power sources to deal with all three chests.

-annoyed-

I’m pretty sure they’re used in sequence, so you’ll just have to get all 11 sources to open all three chests.

All 12* orbs, and I lack an edit button.

Have a look on http://wiki.guildwars2.com/wiki/Scavenger%27s_Chasm
You have to bring the 12 orbs to open the three chest. You can’t open the last one as long as you didn’t open the first two.

and i’m pretty sure there are 12 of orbs in chasm as i’ve gathered them all.

But there is bug on using up all 12 orbs: while it opens all 3 chests(and you can loot them), 1 “lock” remains unlighted and fails you on getting achievement so you have to try again on next day or do that puzzle in 2-day timeframe gathering more than 12 of those orbs.
