Not having tested this, I’d guess C and D would not execute.
You can easily test this with some dummy ActionTasks that wait for some time and then log something into the console. And have a transition that from AnyState to another state, maybe with a key press as a condition. Then debug and look at the logs!
Notice you need implement OnStop in the ActionTasks, depending on how you implement the waiting.
The AnyState transition is immediate and such the current action task will be interrupted/stopped and any other action tasks afterwards (C & D for example here) will be ignored and not execute at all. (All this considering that the actions are set to run in sequence rather than parallel of course).
