I'm in a workshop and can't see you file. But here's what you can try.
Option 1:
- Create a trigger to jump to that slide.
- Set the properties to reset to initial state.
- That should reload the slide.
Option 2:
- Make sure the motion path is locked
- Add a new motion path, set the path width and height to 0. You should see no path line, just a dot.
- Put that dot in the starting spot and lock it.
- Add a replay button and include the trigger to move the rocket on that motion path when clicked. The motion path won't move because it's 0,0 but it will move the object to the path.
