Chatting with @raz0rbackzwei about applying the various fixes listed herein, it made us realise there was a top tip we had failed to convey. Most of the changes listed in this document can be applied to an element and then updated across the scenes that use it using Update Mode. It's just a question of how you've gone about constructing your scenes. Bigger projects are likely to make more use of elements. It's these sorts of projects that can benefit most from this tip.
An example of this method is discussed for Cone wars in this section broken base poses.
Here is another example using @raz0rbackzwei's Mimeo Prophecy as an example to fix a text issue by editing and then updating elements.
