[@Double Capybara] If it does deviate again, at the very least we'll have a concrete idea of how far in the past or future each storyline is. This isn't about restraining anyone from going as far ahead or from staying as far behind as they want, it's all about actually knowing where in time each storyline is taking place and ensuring that each plot is actually being consistent with itself regarding its timing. That's all this really is. Other than putting a small date in the header, nothing substantially changes.
