Anyone here done Underbog? Help, I'm puzzled at this! Secret place?

I'm farming for herbs and Sanguine Hibiscus and this is the third such herb I've come across that I can see NO way to reach. I've taken screen shots and labeled them as such so you can see what I mean. I'm trying to figure out if there's a secret section or maybe another whole section I'm not seeing at all??

I've never fully done Ub with a group to the end but in these pics I'm just around the corner from The Black Stalker on the upper level. If you can distinguish where I am by looking at the pics, can you tell me how the heck I'm supposed to reach that herb?? Is there in fact another level I'm not reaching??

Thanks in advance for any helpful tips... it's boggling my mind and driving me crazy!

To my knowledge there isn't any additional or higher levels in UB. Could very well just been a glitch in the spawn.

That said, I have had no problems with the herbs in UB spawning for me :)

Weird... /sigh. It's spawned there 3 times now though...

There's a lot of copper nodes in Mulgore that are not reachable at all, sometimes herbs and ore are placed in stupid spots.
