Server seems to not be saving, rolls back
Last Month My Server Started Randomly RollingBack like 9-10 hours, My server.saveinterval is set to 600 it auto saves every 10 minutes, But somehow when the Server restarts daily at 6am it Rolls back like 9-10 Hours! Any idea what could've happend? I've ran the Server for about 5 months nearly 100 days no Issues until Now! Thanks for any Help. 
I also had the same issue hops this wipe its resolved.
Just wiped my Server yesterday and its already happened again over night! So its not Resolved yet!
Who is your server host
I use Scalacube dedicated, 32gb ram, 8 core Cpu, 100 player server
Ya i use difrent humm.. i wonder what could be making the saves not save maby the map? you using the same map as last wipe?
No! I change maps every wipe. I disabled my Automatic Daily Restart to see if that Fixes the problem.
I had the same problem through gtx gaming then I started to use the RCON 

In Rcon or in game f1 console you can type restart 3200 when the timer is finished it will restart it without a roll back. Also when at the last second when it does restart it will save it but I recommend adding a command for every 10 minutes for it to auto save 
To stop the restart type restart -1 

This solved my issue I recommend avoiding the hosts control panel
Thats my Plans! Thanks, I disabled my Auto restart feature, I'll be using F1 and Restarting it manually from now on!

I just seen in my RCON when i do server.save it says Invalidate Network Cache took 0.01 seconds, What does this mean??
Type save only. Works for me

Also do you use save announcer? I prefer using it since it lets players know when the server saves
im not using the host to auto restart im using smoothrestarter .
I think i figured out why my server Rolls back, I been monitoring the RCON and the server.saveinterval stops working after awhile, it saves every 10 minutes for awhile but then stops saving, What could that be? 
I had this issue, turned out my server would restart due to low ram and interrupt server saves and giving me rollbacks
mines got 32gb dedicated i've got server.saveinterval set to 600 (every 10 minutes) it just quits saving all out of nowhere! 
Are you using Rust Admin?

If yes make a scheduled command called "save" and set it on periodic and set the timer for 10 minutes then type save then click create.
