I keep running into an issue with AG Reborn corrupting saves. After a day or two of playing it on a restart the server will not come back up. Where do I start in figuring out what's causing the corruption?

Start with AG Reborn's forum / discord / steam page. It may be a documented / known issue.

My servers run this mod i havent any problem

This mod usted total conversión dont ned clássicflayer for example

Thanks guys, I figured it out. It was Automated Ark 3. Automated Ark 2 works fine for whatever reason.
