Super Game Idea - durability of the bomb, however, at risk

So the game is SUPER !!! Absolutely amazing for just about every age appropriate. I am so begeister of this game that I have now given it away already 3 times. The feedback of the recipient was always absolutely positive.
The only drawback to this game is, unfortunately, the bomb itself. In my game after 5 minutes, the screw has fallen out of the bomb ground. But my husband was thankfully a bit more pure screw - since it holds. But already mentioned in the other Rezesionen, is what this game fro sometimes hot and the bomb is thrown but times. There of course is inevitable that the bomb goes down sometimes. Rubber or other durable material bomb would have made more sense here.
