Why do Streaming Levels/Streamed actors appear for 1-2 seconds then disappear?

Development Programming & Scripting

I have 2 streaming levels that work on 2 Sphere brushes. However, the spheres disappear 1-2 seconds after loading. I can load them as many times as I want in the game but they disappear shortly after loading every time.

Here is my load/unload code, though I changed it to have the levels unload only on EndOverlap and extended the triggers to cover the entire level but it didn’t help.

Streaming usage is set to SVB Loading and Visibility.

Streaming method is set to Blueprint.

Just noticed it leaving a shadow behind… Doesn’t do it every time. Will have to investigate that tomorrow… -_-

I don’t have a clue about this disappearing act. Anyone?
