Good to know on the log, because yes, I had it open. I'll make sure the log isn't open when I do that.
As for settings, everything is default except 2 things: Mods (Just 5 relatively common ones), and I just noticed the "Server Files" is set to a drive instead of user, so I'll try changing that to see if it has any impact.

To: /mnt/user/appdata/conanexiles/
Edit: And either way, if it does it again, I'll just run the native Windows client on my VM. Either way, thanks for all the great work you do! The Valheim one has worked great so far!
