Fire float at air - cannot control or see it until full render

I have many fire emitters constrained to books in this scene, it works ok in real-time and in PT playback:

But when I render this at render farm or in my local PC with A6000 I get extra fire “floating” at air. See here:

Can I send you the scene so you could take a look what cause this?

Hi @pekka.varis! Yes! Please send me your file here: and I’ll have the dev team take a look!

Thanks Wendy! I sent the scene.
