Some time ago I posted about some particles not behaving correctly when using contacts to activate them. Basically the problem was that I'd slash through someone, have the particle trigger once and a sound go, then every other slash would trigger just the sound despite that being triggered in the same animation. Someone suggested to put on "always simulate" but that didn't help. I can say that I have now figured out the problem. Pic related if it's set to "destroy" will completely delete the particle system after it has played, preventing it from being played again as there is no particle system to toggle back on.

I want to fucking kill myself.
