Hi,

that's not really a bug but a feature to ensure that the ServerConfig.json doesn't contain unused parameter. In the past we had server operators wondering about various config parameters which were either no longer used or added by mods.

Thus it's not considered good practise for mods to add parameters to the ServerConfig.json but recommended to use a seperate config file.

But if you really want to add parameters to it you can by overwriting LoadConfigFile and adding your mod's parameters to the defaultConfig table when the server config is loaded.

Last but not least you should have a look at Shine's ping tracker plugin which basically offers the same features as your mod. See https://github.com/Person8880/Shine/wiki/Ping-Tracker
