Object Intersect not working when grouped
I'm a new user to Storyline and have been trying to get some mechanics to work for an xmas game I was planning on making.
I have a rectangle (attached screens) which moves up or down the screen and when it collides with one of the explosions changes the state of the explosion.
I've created a graphic that's larger than the canvas and have an animation for it to slowly move from left to right, giving the impression the rectangle is move along it. I want the explosions to move in sync with the background so created a group and applied the animation to the group.
When I do this and preview it I just get a white blank preview (screen attached).
I tested it by removing one of the explosions from the group and turning off the triggers for the other explosions and it previewed fine.
1. Is this a bug with Storyline?
2. Is there any other way around it, other than adding animations to each explosion (I'd ideally like to avoid this).
