(BUG) Unload stream level node never completes

I have encountered this issue before, but it isn’t consistent enough, you can’t replicate it 100%;
The issue is, sometimes a level that I am unloading using ‘Unload Stream level’ blueprint node will get unloaded properly, BUT the node itself will never return ‘completed’, which means my blueprint will stop running at that point, and nothing that comes after will ever get executed.

The level name matches exactly and the level does unload, but the node won’t return;
It’s worth mentioning too that the level has solely a directional light and a sky light, so it should unload basically instantly (much bigger levels unload in no time);

Have anyone else had this problem before?

Did you ever find the solution to this problem?

No, but we were using huge levels at the time, maybe it wouldn’t ever unload because it would get suck at an infinite loop or a bad piece of code.
I would just branch out everytime I would unload a map.

Hey,

I had a similar issue, and after some searching I figured out that the actor that called UnloadStreamLevel was IN the sublevel that got streamed out, this way it was never able to call the rest of it’s own blueprint.
By moving the actor to a different sublevel, everything worked back as expected.

Hope this helps anyone coming across this post :slight_smile:

Hey maranbe0,

I’ve attempted to reproduce the issue in a clean project on my end, but I haven’t been able to replicate your results.

I have a few questions:

  • Could you please provide the log from your project’s Saved->Logs folder the next time the issue occurs?
  • Also, could you attempt to reproduce this in a clean project and provide me with a consistent set of repro steps I can follow to get this to occur on my end?

Thanks
