Mechanics Bug

I have a coaster that has broken down and the mechanic will not respond to fix. They guests are still stuck on it, but it is not giving the usual annoying message that it hasn't been fixed, it just seems like the game forgot it is there. I have tried to reset the ride, like you would after a crash, I've tried to assign a different mechanic to it, downloaded the most recent patches, everything I could think of. I don't really want to have to demolish it because it uses several tunnels and would be a pain to rebuild. It is also one half of a dueling wooden so I don't want to leave the other half alone. I tried to demolish and just drop a clone in, but of course it places it above the ground instead of in the tunnels. Is there a way to correct this problem that anyone has found.

I've never had that kind of problem.What I do is station mechanics at the exit of each and every ride that I build.If the ride is a dueling coaster then I put one mechanic at each exit.If it is a transport ride such as a railroad or monorail then I put a mechanic at each individual station along the ride route.Sometimes the mechanics still don't respond and I just fire them and replace them with a new one.Try that and see if it works.
