Making a level stream blueprint. No errors during compilation; however, I get a compilation error on hitting "play. Any suggestions on what I could be doing wrong, or how to level stream more effectively?

I’m trying to stream a level by streaming separate elements within the level. I have a Bedroom level, Bedroom lights level, a hall level, and two more level elements for the decor and foliage/tables in the hall. I assumed, since streaming levels makes a game run more smoothly, maybe streaming the components of a level might also do the same thing. I’m not sure if that’s a bad, illogical, idea.

When I compile my blueprint to stream the levels and their elements (or not stream them), I don;t get a compilation error, but when I play to test the game, I get a compilation error on “hall”. Pics are included. Please let me know if there’s a way I can fix this or if there’s a better way to create my level stream blueprint.

Order of pics: hall compile error on play; hall compile error; hall compile error 2; hall compile error 3.

I’ve been stuck on this for two hours and don’t know what else to do. Any help would be appreciated at this point.

Never mind, error resolved. I had an unsaved blueprint on the “hall” level element. It was closed and I forgot about it.
