Hello!
I was looking for a way to handle all player`s COMPLETED actions, so I choose ActionBaseCB and wrote the following code:

modded class ActionBaseCB {
    override void OnFinish(bool pCanceled) {
        Print("pCanceled: " + pCanceled);

        if (GetGame().IsServer() && !pCanceled) {
            // ... my code ...
        }

        super.OnFinish(pCanceled);
    }
}

Next, I choose ActionDigWorms to test it (with HuntingKnife).

Expected results:

1. Started dig worms and finished it: pCanceled == true
2. Started dig worms and cancelled it in the middle of process: pCanceled == false
3. Started dig worms and cancelled it berfore process started: pCanceled == false

Actual results:

1. Started dig worms and finished it: pCanceled == false
2. Started dig worms and cancelled it in the middle of process: pCanceled == false
3. Started dig worms and cancelled it berfore process started: pCanceled == false

Is it bug?
