This is the error I keep getting when trying to play the mod. Hope you can fix it, mod looks cool.

That looks like some mod you have is modifying the vanilla rocket ammo. Do you have mods you think could be the culprit?
Basically what I do is copy the vanilla rocket and inject/modify some stuff. But if the vanilla rocket was modified before I could copy it, then my modifications can target a nil value, causing an error.
I should probably switch to just fully explicit ammo definitions, then these things wouldn't ever happen.
Merry christmas!

Try the new version and let me know if it works!
