Blueprint errors when ever I reload my project

Hi, I’m really not sure how or why this is happening but when ever I open my project a blueprint returns an error.
The bellow image shows where the errors are appearing. I can fix this by recreating the nodes but this is a bit of an annoyance having to recreate every single time i load the project.
All that section does is compare the meshes in the array with a blank mesh and another mesh.

Any one got an ideas?


Ok, After literally an extra minute of playing around with it I have discovered 2 things.

Dragging from the “Hit Component” allows me to create a node which attaches to the Make Array.
Dragging from the “Make Array” doesn’t allow me to connect the created node to “Hit Component”.

Is there another way of getting the mesh of the hit component?
