Insistent Salvage

Another problem, {username}, is that instead of properly recycling old robots, they're just being tossed out now! Many of them are workable enough to continue functioning for a while... Perhaps they're gathering near the pylons because they're attracted by free energy, the emissions of the manarail... but that doesn't matter!
They need to be dealt with before they damage a train or the pylons. Get a dozen dismantled, and the rest will surely scatter.

Robots! Soon, I heard, we'll be facing the true rise of the robots!

Excellent − it seems the robots have scattered, which means the threat is removed!
