Heya,
Decided to publish one of my tiny plugins - ActorSingleton
It adds one C++/BP class that can be derived of. It ensures that said class will be spawned only once within World context. If you try to spawn more, you’ll get an error/message about it. This is an alternative to UWorldSubsystem.
Hope, it will be helpful for someone.
Cheers!
