I think what's happening is that the Distribution Builder is adding a hidden
group for Rev libraries, so if this is the first card of the maintStack
there is very likely a 21st group.

If so, I don't think it's the attempt to reference the 21st group that's
causing the crash.  What exactly are you doing with the groups, and is it a
true crash or an error?
