Oh man, I just encountered this issue while playing on the xbox. I spent an hour or two re-tracing my steps thinking I missed something. I am getting this same msg when I try to set the explosives, but in the southern mine.
Any updates on a fix for this ? I am enjoying the game a lot, but this is aggravating. I hope the programmers can release a fix soon ? Obsidian, please fix
Thank you
Paul
