I'm trying to create a quest but the page won't load. I've logged out and back in, closed and reopened the page, reloaded, made a new quest. Why won't it load? If it doesn't have the word 'loading' on the screen it's just a blank page.

Are you using the web editor?

Seems to be working for me.

My best guess is that it was a temporary glitch and is now resolved; or that an adblocker or some other user script is interfering with the page (Browser extensions can be pretty useful, but sometimes they don't play nicely with more complex web apps.
