Just noticed that editing the values on a noise controller (on a gravity if that matters) doesn't cause tyFlow to recognize a change and re-cache. Specifically, I changed the entire controller to be > 0 and it didn't update. Seems like it should be recognized and force an update.
So I created a simple icon flow, added a force operator, and then assigned a noise float controller to the gravity strength and popped open the noise float settings...then when I change the strength value, after each change the flow updates properly.
So if you could send your scene file to support@tyflow.com I can check out why it's not working on your end.
