Set sprite flicks immediately

So on content we have an issue where the animation is played in doorsystem but sprite visibility is controlled by airlocksystem. The issue then is that we get a single frame where the incorrect sprite is shown before it corrects itself. The easiest way to reproduce this is to walk into a door that denies you and observe it shows the incorrect sprite then flickers to the denied one.

There might be more systems with these issues which is why I did this here instead.
