Darkrime Delves

i need help, im in the second level of darkrime delves and reach the area where the boss key should be. kill the foes there and no key is present. a boss wasnt there either to kill for a key. is this a bug? also there is a lockchest too but doubt anet would put a boss key there. I dont have any lockpicks with me so this is annoying me.

Yes there is a bug, confirmed on Guildwiki:

Quote: Bug! The boss on the second level, Grelk Icelash, occasionally does not spawn. Note that this boss holds the Boss Key, and it cannot be obtained without the boss being there itself. So your stuck, you have to /resign and start again, sorry.

thats just great, i used a powerstone like right before to fight all of them.
