Unable to load saved config in 5.5

I have a 5.3/5.4 plugin that I’m trying to add 5.5 support to. I’m encountering an issue when reading config settings from the saved directory. When spawning an instance of the settings object, the members are all set to empty. In 5.3/5.4, they would be populated from the INI file.

My settings file is a UObject with some public data:

UCLASS(Config = MyPlugin)
class MYPLUGIN UCharacterSettings : public UObject
{
	GENERATED_BODY()
public:
#if WITH_EDITOR
	// Called when a property on this object has been modified externally
	virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;
#endif

	// The path of the last used Character file
	UPROPERTY(Config)
	FString CharacterFilePath;
}

I create a default instance of this whenever it is needed. The data is then read/modified, and re-saved. Strangely, in 5.5, the initial values are empty, but once they are set and saved, it does update the INI file correctly. It also retains the edited information when read later. Once the editor is restarted, it is all empty again.

// Get the currently stored settings
UCharacterSettings* CharacterSettings = GetMutableDefault<UCharacterSettings>();

// Do some stuff

// Save changes
CharacterSettings->SaveConfig();

I’ve also tried using the GetIni command, to read the data directly from the file. Prior to editing the settings data, it will also return empty. Once the data has been edited and saved, it does return the correct values until the editor is restarted.

I have tried manually calling LoadConfig() on the instance prior to reading from it, however this does not appear to make any difference. The file name appears to be correct when saving, so I don’t think it fails to load for that reason.

Does anyone have an idea about what may be causing this?

Same problem.

I ended up manually pre-loading the config file. This involved getting the path to my ini file, loading it into GConfig, then creating an instance of the settings object and calling load config on it.

I’m not sure this is the best solution, but it does resolve the problem for now.

// Get the INI path from <ProjectDir>/Save/Config/<Platform>/MyPlugin.ini 
FString ConfigPath = FPaths::ConvertRelativePathToFull(FPaths::Combine(FPaths::ProjectSavedDir(), TEXT("Config"), FPlatformProperties::PlatformName(), TEXT("MyPlugin.ini")));

// Attempt to load the config file
GConfig->LoadFile(ConfigPath);

// Populate settings object from loaded data
UCharacterSettings * CharacterSettings = GetMutableDefault<UCharacterSettings >();
UCharacterSettings ->LoadConfig();
