This solved it for the tyCache.

And now I have the same problem with the tyFlow imported into a BirthFlow.
But the tyFlow node has not the same settings like the tyCache node with "Subframe scale down".

So my simulations needs to be cached - or any hidden settings?

I looked through my years old detailed documentations, there was never this issue, this must be something new...

Thanks
