Reference viewer showing garbage stuff

How can I get rid of that?

This is pure garbage. These objects/assets/classes doesn’t exist and there is nothing similar to that when I open the blueprint editors.

I can’t pack my game because of these stuff. The game works fine in the editor, btw.

i think your assets that you import to Unreal are outside of content folder, so when u package or launch the game, engine couldnot find them, is it true?

Nope. That’s nothing wrong, it’s garbage probably caused by the hot reload (I think).

Anyway, I just realize how to fix that: I just need to change anything on the blueprint (like unpin something and then pin again) and click the Compile button and it’s done: the weird stuff is vanished.
