The death of a particle is delayed after hitting a wall

Hello!

I made a simple Niagara system with three emitters: Head, FollowingGlow (which follows the head) and the OnDeathGlow which is spawned after the death of the HeadEmitter.
I have an issue that there is a delay between the particle hitting the wall and disappearing (its death). The Head emitter has collision detection and it generates death event correctly, but I couldn’t find there anything about the delay. This issue also occurs after packaging the project. Screens of the Niagara system and a video showing the issue below.

Okey, there was a delay, because the particle died after the end of a lifetime, not when the collision was detected. I added “Kill Particles” to the Head and set it to “HasCollided”, then everything worked as it supposed to. Screens:
