Particle children “simple” stop showing on certain frame

Question

I'm simulating particles with boolean object as the emitter and icosphere as particle.

Adding simple children was fine, but when it hits a certain frame (43 to be exact), the children just gone on display and in render.

Tried several things that I thought could've been the quirk, like;

• changing numbers of particles,
• moving the boolean mesh so it won't completely disappear
• deleting cache manually

Anything I should tweak? Or is there a workaround?

Thanks in advance

Just found out, the culprit is the Boolean. Tweak translation of intersecting objects to make it work.
