Ribbon Renderer Tails Bugging When Receiving Location Event

I have a basic emitter that spawns particles and another emitter that creates ribbon trails behind them.
for some reason, the tails of the ribbon get all wonky at their ends.

Does anyone know why or how this happens and how to fix it?

thanks in advance

Have you enabled “require persistent IDs” in the source emitter properties?

yes persistent ID’s are enabled

it turns out I need to check “Use GPUInit”

however system seems to destabilize if the ribbon particles have a lifetime greater than 1.0 ? :face_with_monocle:
