I was exploring the Hoover Dam out of curiosity and found a strange switch I could pull.. so I pulled it!

However, when I'm doing the last mission, I return to the switch, only to find that I can not turn it on 'again' and the mission will not be displayed as done!



Is there any way of resetting the "pull flag" for the switch? or do I have to start a new game and make sure that I do not pull the leaver before I get the mission?

Yours,
