Niagara messing with Cloth Simulation assets?

I set up a Niagara System to spawn when an enemy with ‘tails’ dies, but as soon as the particles go off, all the tails become wonky, buggy, straigthen out and the game chugs down to 2 FPS.

Now, even if I don’t set up the System to spawn when the enemy dies, if I place the same Niagara System on the scene, whenever I play all the tails fail and same thing happens.

From my limited knowledge, it almost seems that having the Niagara system in the scene is just completely messing with my cloth ‘tail’ assets.

As soon as I delete the Niagara System from the scene everything runs perfectly.

Clearly I’m missing something here… What is it that could be killing my scene when using Niagara? Especially how it kills all the cloth sims…
