Not sure if you have multiple admins, but there are 2 things in your save folder.
Userdata
and the map.

The map itself can be deleted and userdata intact.
That is what I believe happened.
If not then I am not sure as the new update did not wipe my server map.

Sounds like update wiped save folder. Hope your admin makes local backups.
