Niagara Maintaining Constant Particle Count and Respawning Particles on Collision

I encountered an issue where I couldn’t find the HasCollided boolean inside the MapGet node in the Scratch Pad for the Kill Particles module.

That said, I was still able to use the boolean as an input value by selecting it from the dropdown menu. I’m not sure if this is a bug or if I might have overlooked something.

Aside from that, this works perfectly and achieves exactly what I was looking for. Thank you so much for your thorough and detailed response!
