Communicating with sublevel through blueprints

I am using level streaming and I have some actors that I want to run blueprint functions on from the persistent level.
I tried to use ‘Get All Actors Of Class’ from my game mode but it only returned actors in the persistent level.
And I have not found a way to access the sublevels level blueprint from the persistent level.

I am using the level streaming to build a procedural level that is different every time.

Anyone know of anything that might help me?

After some more testing it does seem like the ‘Get All Actors Of Class’ node did work but only after a delay of over half a second after the loading of the level.
I’m not yet sure why I need the delay nor if it is even safe to use a delay or if it depends on the loading time of the level.
