It was almost a non-issue for CE, since only one person was actually coding the game at one time. But if you examine the CE forum, by volume it's one of the bigger forums on the Chrono Compendium. We posted often.
The project needs a champion or perhaps a duo to coordinate all the activity and swat down bad suggestions or implement new ones, so it's sort of a case of the Byzantine Empire. If you have a good emperor, the rest of the system works well; you conquer lands, grow themes, and promote trade. But one bad emperor can lose the entire empire, and when the project champion isn't active for whatever reason, things can get messy unless there's a good system in place.
With Crisis, it sounds like Chains wanted to be in control of every decision and piece of work, but wasn't nearly active enough to make that possible. So, without a good idea of what they could or should do, the team had nowhere to go. With CE, the plot was cleanly laid out, so coders and mappers could create areas even if the directors were missing in action. There's enough final scene tweaking and polishing done that it's almost stupid not to map things out in advance for the reason of "avoiding revision work when the directors come back." And if the directors are always missing, perhaps they don't deserve to be calling the shots on the project to begin with.
