Had the same thing happen to me some years ago. Had a (not so important) domain with Gandi, which pointed to the Cloudflare nameservers, and after some time, the domain was gone from the CF dashboard together with all DNS entries. The NS records were still pointing to CF and there also weren't any anomalies with renewal of the domain. I didn't give much thought to it, as I wasn't using CF for anything in production at the time, but sad to see that it also seems to happen to other people.
