According to jsonlint.com, your file is not valid JSON as it is missing a closing } at the end. Not having a valid configuration file (invalid JSON) would cause most plugins to reset to defaults.

It didn't copy/paste the final }. All are working now but for 2 barrels. the "assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-1" and "assets/bundled/prefabs/autospawn/resource/loot/loot-barrel-2" they are vanilla though they are set in loottable
