Move event number 10 to top level, it doesn't need to be nested under "Every tick".
It's not possible to guess what the problem is by the screenshot. Add another event "On failed to find path -> Mira set opacity to 20". You will see if the pathfinding can't find the path, in this case try changing cell size/padding, check solid objects etc.
You may also need to recalculate the obstacles map.
Also, change Hunt_SalaT2 variable when the path is found, or add another condition to event #8 - "Mira is NOT moving along the path", otherwise it will be trying to finding a new path every tick.
