Other mods that use .toml configs keep getting reset #995

Version information

Kilt 20.1.20

Expected Behavior

Config files should be saved without being reset.

Actual Behavior

Config values, while kept in the current session, always revert back to default when restarting the game.

This also creates a bunch of unnecessary copies of the same config.

Strangely, however, one of the copies are blank.

Reproduction Steps

1. Install a mod that JIJs or uses Forge Config API Port
2. Change a config value
3. Close and open game

Java Provider + Version

Java Runtime Gamma

Additional information

Tested with Create 6.0.8.1, Valkyrien Skies also exhibit this issue.
I have provided two log files due to the issue requiring a restart.

Knowing that there was a fix that got merged, I have reason to believe this is a regression.
