I've been thinking about implementing some 'upgrade' which you could obtain to see the energy cost, though I don't really remember an action which could take 13 energy, what was that?
It was some work event in the club. It's possible it counted as multiple actions because I chose to do the extra thing, which was getting fucked in the restroom, but if so... the energy amount wasn't deducted until after both actions, so that may be a bug?
