Not really. :)
However, we're not expecting the GBC to run 100% of the time. It's not like letting
a train run in a circle for eight hours. There are all kinds of things going on at
the same time. In our testing, we seemed to run for about 20 minutes at a time,
before someone would say, "Stop..."
Then, we'd shut down the contraption, pick-up loose balls, check weak spots, and
power it up, again.
Generally, if one module doesn't work, we'll just take it out, slide the other
modules together, and start going again. Given that there are no "special" modules
(beyond the first and last modules) any other module can be placed in any location.

I'd kind of like to see a module that won't "work" if it's empty. :)
