An expiring domain I am looking at got deindex a few hours before it goes to auction?

Hi! I just want to know if that's still good? An expiring domain I am looking at seems to have a decent backlink profile and no spammy content. I've also checked before that it still has 1 page indexed on google, however this was totally gone just before it gets deleted. Is this normal or should I just scraped it off my list? I am trying to build my first pbn... thanks!
