The fix is now online and can be downloaded with the Epic Launcher. Passing by, I took the opportunity to improve the debugging experience for nested states. This is the appearances of the “Debug Filter” before the update:
In this case, there are multiple objects, running FSMs each in a state implemented by the same class: all state objects are displayed with the same name (the state class name), making it difficult to see which is which. This is the appearance of the filter in this new release:
As you can see, the filter now shows exactly the name of the object running the FSM, the name of the FSM and the name of the state (not of the state class). Hope it helps!
Enjoy!
