Harry Potter energy splash question

Hi everyone.  Brand new to Hitfilm and having a blast.

I downloaded the Harry Potter energy splash tutorial files and tried to apply them to my own footage.  I figured out how to isolate the floor, splatter, and glow into their own embedded composite so that the glow would not affect my footage (saw that suggestion in the YouTube comments).  I got my wants tracked and linked to the ends of the 2 lightning effects.  Everything is looking really good.

Except I cannot get the wildly rotating impact point to link properly to the newly embedded and isolated splatter.  So I just killed all of its motion and now it looks to stagnant.  How do I get that thing flailing correctly again?
