I Think That One Alert isn't Working Properly in my Game

I’m programming a simple game here and this alert is doing problems.

Look on this and tell me if the alert should work:
It just pauses the game and the alert doesn’t show up.

Link to the game: https://flowlab.io/game/view/306599 (The alert is in the white dot block named “Bomb”)

Could someone give me an advice or fix it, please?

Here, I’ve made a video showing the bug: https://www.youtube.com/watch?v=pSbR1c6yzKE&feature=youtu.be

The alert works the first time but when I test it again it will just pause the game.

Hey Juch, I took a look at your behaviors in your “bomb” object. I think that what’s happening right now is that the bomb object is getting destroyed immediately on contact, so its Alert is not being displayed.
