1.13.0.9

Summary:

The execution order of on_exit/on_entry events in animation controller state transitions has been reversed from what it used to be. When switching from one animation state to another, one would expect the on_exit events of the previous state to be run before the on_entry events of the state being transitioned to - and this was the behavior until 1.13.0.9, when the order was reversed.

Impact:

This breaks existing content that relies on the execution order of these events. For example, a fill command as an on_exit event, followed by a teleport command in the on_entry events, would now teleport before the fill command runs, which is unexpected behavior.
