Yes, the full setup would allow me to look into it. Sometimes, that is sadly not a given.

Thanks for your patience

My best wishes for your project!

I think i solved it, i things. I had one volume texture for the 4 explosions, i created one for each. And i thinks it work now

The product is not battle-tested. 😉

If it is based on Multiple volumes, and each sequence has unique names, then it is a case for the tech support.

Seriously, the video shows that things are weird in the second five. Yes, that is the blurry term I would use here, as I can't tell from a video what the setup is.

This effect reminds me of Timing issues when the time goes beyond 100% (overshoot) while the keyframes might show 0%-100%
But that would require two Volume loaders, as the red part stays.

Without the file here, I can see that would be problematic. I can only guess this is not the best way to solve a problem.
Have you retimed Pyro?
The explosion on the right seems to come closer to the middle. Is this moving?

But perhaps that is already a start.

Besides that, the vdb file for the problem frame[s], is it rendering found when placed into a new scene?

Sorry if that is not helping.

Cheers
