Error when AbilitySystemComponent without Interface on Actor

When using the AbilitySytemComponent, it is always crucial to put the AbilitySystemInterface on the Actor that possesses the ASC.
However, people sometimes forget this. It’s a simple error to make and hard to spot. When you forget this, it’s not clear at all what’s broken except that things are not working as it should.
Requires lots of digging around source code to find what the isuse.

Any chance we could get a clear error when you try to use the ASC without the Interface on the Actor?

Thanks a lot in advance.
