for some reason, when they detonate they will sometimes make the mines near them explode too, and sometimes it won't.
Check these screenshot :


Tm-35 health has been decreased by 99% but no explosion.
When i put 2 or more trip wire near a regular mine, it doesn't matter and health will remain to 1%.
Except some times, it will explode but i have no idea why.
I checked mine stats and found that it's related to AOE penetration, when i increase it, i get much more chance that the other mine explodes.
But my aim is to use it in vanilla game, without mod, so i would like to understand how it works and how to increase the chance it makes the other mines explode in normal game.
That's why i am asking some help from modders or people who knows more about game mechanics.
