I have found that at a certain length of steps and complexity Creo Illustrate begins to introduce glitches into sequences. These relate to the position and visibility of parts. The attached video demonstrates this.
1) The pump cover is moved in place
2) A new step is created with the (+) symbol
3) The new step automatically retains a position for the pump cover from 2 steps prior. Instead it should retain the position from the previous step.
I don't have issues like this in shorter assemblies. This is a challenge because it would be best for AR training if we could show all of the steps (start to end) of complete overhaul of our product.
