Failed dragon banner quest bug?

So I've just failed the main storyline because I ran out of time trying to get to clan level 4 in 10 years, but it has only been like 700 days. Is this an intended feature or a bug? Is there anyway I can get around this aside from loading an older save and grinding?

If this isn't a bug it is a real dumb feature having such an important quest on a timer.
