Guild Wars 2

There is an issue with one of the steps in the Spark III achievements list, in Iron Horse Mines. I have the necessary components (i.e. mordrem thrasher gas bladder, etc.) but there is no “pressure” in Iron Horse Mines to be able to commune with and combine these components to create Unstable Miasma. It has been over a week now and I am still stuck on this part. This is very frustrating. I have checked every nook and cranny of this area and have done every event possible and have spent 7 hours just trying to do this one step. If anyone can confirm that this is a bug, or let me know otherwise, that would be great.

I’m having this same issue now. The wiki states the pressure should be found at the bottom of the pit next to the PoI, but I’ve searched everywhere in there and I can’t find anything.
