Gunpowder (Combat Extended)

[TheManWithoutAPlan]

I was playing around with the combat extended mod, and I decided to make a mountain colony so that we'd have tons of supply for ammo.
We were doing good, day forty and we had turrets and such, however everything started to go downhill at one raid.
It was eight raiders, one had an incendiary, one had grenades, everything seemed fine. They entered my kill box, the grenadier decided his life wasn't worth having without a table and rushed towards the fortification where my colonists were. He was shot down by one of our turrets, his stuff was laying on the ground, there were bullets scattered everywhere from present downed raiders, or past dead raiders.
The grenadier is laying on the ground, slowly dying. All my colonists are opening fire with the turrets doing most of the suppression job. Things are going great, we're getting ammo from the side ammo rack (A room connected to our kill box) then the incendiary man finally gets the balls to fire.
I see the incendiary raider take aim at one of my colonists, Rasputin, and open fire. I watch the fuel cell completely miss, but then I see it heads toward the grenade. Now I had no idea about this nifty little feature.
In Combat Extended if any ammunition is lit aflame, it starts to fire out like a grenade, grenades are triggered by fire as well.
The flame cell hits the grenades, and starts scattering all 19 of them and like 50 pieces of shrapnel each across my kill box. This turns into a chain reaction, as the bullets hit the bullets on the ground they start firing, then they down more raiders and colonists which drops more ammo and lights more ammo.
When the grenades lit up, I saw Rasputin's health tab go from spotless to
Head : Shredded (1/30)
Neck: Shredded (1/30)
All of my colonists are downed in almost five seconds, the bullet chain reactions starts moving along, and everything is just bad.
You know those bullet hell games? Yeah this is what was happening in that 15 by 15 kill box, but the worst part about it was just the sheer absurdity of what was happening. Bullets were being fired everywhere, I swear I counted over 1500+ rounds being fired in every direction. The sheer blast of the bullets was enough to dig holes into the kill box, which also dug a hole into my ammo rack. Almost simultaneously the fire spread to my ammo rack, as the fire had not been idle this whole time and had been jumping from colonist to colonist to raider to ammo like a jumping flea. My ammo rack starts going crazy, more bullets being scattered everywhere.
I had around 2500+ different ammunition in that ammo rack alone, including BMG rounds which tore through the base.
At the end of that raid not only was my colony annihilated, but as the fire spread through the base via flammable wires and flammable steel walls, I was left there to wonder how could this have happened. I watched the last prisoners die not by the thousands of bullets slowly flooding into the base, but by the rising temperature within that mountain.
The colony Bunker Eleven went from an underground safe haven to an underground hellhole.
And it was all because of that god damn gunpowder.
