Sucks, but sounds like they’re taking the right steps. I have a little experience with animation graphs, but enough to know that making major updates to the player graph in a live, multiplayer game is a fucking nightmare to debug. The complexity increase is exponential because new states must play nice with many, many existing states and transitions. It’s also hard to automate testing. Also parts of the animation system run in background threads so you can get race conditions. Players find that a particular input fails to trigger some flag that it should and you are now in uncharted territory, and fixing it potentially involves large logic reworks. Fun times.
