This mod simply override the stack size of artillery shell from 1 to 20, it's also override the ammo stack limit of the artillery turret from 15 to 20 and the ammo stack limit of artillery wagon from 100 to 20. You can change these default value with startup mod options. This should be safe to install or remove on any game.

Why ?

There is already some mod that do it but there are big mod that change a lot of thing, this mod only do that.
Stack size of artillery shell is weirdly at 1, most ammo stack at 200, while artillery shell should probably have less that 200, I think 1 is way too little, also it's make no sense that artillery wagon can fit 100 while cargo wagon can only fit 40.
