Need help with a fractured wall in delve

Hi! Sorry for the delay, I gave up on the fractured wall last league but basically I reloaded multiple instances of the nodes around that hidden currency node, but never found anything after a few hours.... So my guess would be Niko's mineshaft should've been where the wall is but when he dug the shaft it "bricked" that fractured wall location. I've gotten much better at delve since then and having a lot of fun spelunking in this league haha. Have a good one!
