Hi Thomas, yes there have been two ways, but I would have to look into my notice book and test myself, it’s long ago 
Maybe set the mesh operator to: „Render as mesh“ not instances or vice versa.
And try a modifier on tyflow (not important which)
Or disable GPU instancing in the tyflow render settings
Something of these settings had caused, but not sure what exact.
I had the problem especially with tycached particles and it was easy to solve.
