I've been running bakery continuously for about 5 days, with production at roughly 500bn CPS. Occasionally over the past few days I would reload the page, no problem. Today however after reloading, the app appears to have a different theme (based on the US dollar), and the names and icons for each of the generators is different. For example, before reloading, I had Clickers, Grandmas and Prisms (etc.), after reloading these are now Rolling Pins, Ovens and Corporate Countries. The descriptions still talk about Clickers, Grandmas, etc., my CPS is the same, and I am still in full Grandmapocalypse (which is strange as my Grandmas have been replaced by Ovens)...
For the sake of argument, I just tried loading CookieClicker in another browser and the US dollar theme is there too.
Is there some kind of upgrade going on today?
