Had the same or very similar issue . My domain registrar dropped all name server settings on an 'update'/whois update requirmet change Luckily I had an old export of DNS records so most were there but not all the settings were retained like DNS only or full proxy. Those were not mission critical, so not that bad but I bet some emails went to the void because there was no real warning from both my domain registration service provider and cf so I found it very 'upsetting' (I was pissed on them both)
