If you left BucketPilot open in a tab and we shipped a release underneath you, the next page you clicked into could come up blank — no error, no message, nothing but a white panel until you reloaded.

What was actually wrong. The app is split up so that each page's code is only fetched when you go to it, and a release renames those files. A tab loaded before the release asks for a file that no longer exists, gets a 404, and the app had nowhere to put that failure — so it unmounted everything.

Now a page that can't fetch itself reloads exactly once, lands on the page you were going to, and can never get stuck in a loop reloading. If anything else goes wrong on the way, you get a screen that says what happened and a Reload button, instead of white.

It was reported to us as "the credentials page goes white after a deployment". It was never that page — it was whichever page you happened to open first.
