Niagara System callback collision event not working with different parent scale

I have a niagara system spike effect where I attach a callback to its collision to damage enemies that collide with it. This works fine when the player (parent actor) of the niagara effect is scale 1.0. When the scale of the player is increased to 1.3, it appears to screw up the collision radius of the spikes and they no longer collide with enemies properly, even though the visual effect itself remains the same.

Anyone know a fix for this? This is on UE 5.1
