Is there a way to "step" through the board designer similar to VBA code?  Rather than having to start a game it would be nice to have a way to test elements of the board by stepping through.  I'd imagine a window that would display the code of what's happening to help with debugging.

For example, I'm trying to see how the factory sequence goes given a certain initial setup.  It would be nice to step through this sequence similar to viewing the game history.

Easiest way is to set up a dev game with the preconditions you want to test and then restart the game each time you adjust the parameters. You can see from the game log the sequence in which the events fire.
