I understand what you're saying, but no, I am not mixing up servers and it was definitely there. It was the server I played on with my daughter.
As I said, I was in it recently to update my mods. I even listed the dates up there. But the server I havent been in.. is much older and I was not in it due to errors that I wasn't sure how to fix. I would not have been surprised if that one had been deleted due to non-use.. but it's still there. The deleted one that the one I'm writing about, I definitely was in.
It seems there is no hope in restoring it and I saw my pc going bad on me and that just happened to be a file I didn't get the chance to backup before it went completely kaput.
Thank you all for the information though. I'll definitely remember to backup the new server.
