Vintage Story only keeps 5 archived log files before overwriting the oldest ones. This mod fixes that limitation by adding the command /backuparchivedlogs

When used, it copies everything from Logs/Archive into a new folder inside LogBackup. Each backup is saved in its own folder with the current date and time in the name, so you can keep as many backups as you want without losing older logs.

Lightweight and simple just install and run the command whenever you want to save your logs.
