So in the lvl 2 of Durgan's Battery at the bottom left room there are 8 hidden durgan steel ignots hidden in the mining cart. My rogue has 14 mechanics, so it should be showing. And i know i already did not loot the secret already because it shows up in my game that nothing is there. However i know for a fact that there is a secret there because i just watched a guy in a video loot the hidden Ignots.

You need to find a note from a hidden frozen dwarf on level 1. Only after you've read it can you find the ingots.

Hello

For me it is Owyna hidden ingot which are not showing, I have 13 Mechanic, and I know the location in The Iron Flail, but no way, I can't detect the hidden bag in the stump...

is something required for those ingot to be here ? (I awakened Owyna in WM1)..
