Happened to me a few times this week: I try to run an SEDE query, get this error
Something unexpected went wrong while running your query. Don't worry, blame is already being assigned.
while in fact it just needs a Cloudflare verification. It would be be much clearer to state so instead of a vague "blame is already being assigned" (What blame? To whom? How long should I wait? What do I do in the meantime? etc.).
Feature request: make that message clearer in such cases, or even better, show the Cloudflare verification.
