I will refer you to this post I made just today. Now, in your specific case the part about not having an issue doesn’t really apply, however the issue isn’t necessarily due to the load order. It might be due to an outdated mod or other random issues.
Also that message you got from the log is just a warning, attaching the full log with the upload button might help, or if it’s too long then pretty much the last 50-100 lines at least.
A clarification here might also be important “I keep having random crashes with my server” does this imply that your game client crashes while being connected to your server? Or that your server crashes and disconnects everyone?
