Upon restart of server after the tps gets low, I run /save-all, and once that is complete, /restart. This for some reason occasionally rolls back play on the server anywhere from a few minutes to a few hours, which is really upsetting for some of the players on the server. I've attached a log from just a little bit ago where it rolled back about 10 minutes. I read through the errors towards the end and I'm not really sure what to make of it.
Just wondering what, if anything, I can do to fix this problem as I know I'm using a bit of an outdated version. I am very weary about updating to a newer build for 1.13.1 because there are a lot of players on the server lately. I don't want the server to become unstable or have plugin issues.
