Hi @carramone ,
I had a look, but wasn’t able to figure out what exactly you were doing (yet).
Mostly, I think you made it too complex (“Too many Nodes, dear Sir, too many Nodes.”).
Here is your file, after removing some of them. I also removed the Drivers.
Basically, I Instance the Poles and Horses, make the Horses go up and down and then Rotate the whole Merry-go-Round at the end.
Here’s my version (it’s called Fixed, but that’s not really an accurate name😉):

Hopefully you find this helpful.
