Overlapping doesn't work when toggle visible and player already in the area

[Est_engine]

@Arkenophas

Hey all,
Just making another topic, because, after I fixed my problem with lights here, I noticed something that happen for my lights, and for a monster. I use the BeginOverlap nodes for a bit everything, but, some of the collision spheres are not visible until the player do something. And the problem appear when the player is already in the area of the collision sphere (that is still hidden), and when the sphere turn visible, the BeginOverlap doesn’t trigger, I guess because the player never really entered the area, as he was already in. It happen too for my monster, the player can flash him and make him stop, but when the player activate the flash and that the monster is already in the collision, nothing happen.
So, is there a way to get passed that ?
Thanks for your answers !

You can do some thigns:

1 , use the node, is overlapping actor, to ask directly if the player is in the area, without need for the begin-end-overlap

Is Overlapping Actor

2 you can leave the areas, always active and hide only the light or the mesh,
create another step in the blueprint, to make the area, record the player presence, but , only if he is visible, call a custom event to do some action.
