The plugin doesnt load on start I need to do oxide.reload StackSizeController

This is the error I get

Console: StackSizeController.cs(205,22): warning CS0114: `Oxide.Plugins.StackSizeController.SaveConfig()' hides inherited member `Oxide.Core.Plugins.Plugin.SaveConfig()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword
C:\rustserver\Oxide.Core.dll (Location of the symbol related to previous warning)​

That isn't an error, that is a compiler warning and not an issue. Please check your other logs.
