Technical Issues I ran into while doing my animations

Of course while doing my animations I ran into issues. For example during my second animation containing the Dominoes, I was unable to add anything to it without completely displacing the core of it.

The problem I had lies primarily on the platform on which the Dominoes sit. Anytime I added something (for example a pillar for this platform) it would displace it thus making the dominoes float rather than stand on it. What was disappointing was I couldn't have the start I wanted and had originally planned though that was a fault on my behalf as had made the silly mistake of forgetting to include this in the first place.

Other than this I haven't really run into any other major technical difficulties in my animations so far.
