I'm not sure exactly what the cause of this seems to be, but it happened after adding shield expansion.
It would seem this crash is a combination between some fuckery going on with this mod, oreganized, and shield expansion. This mod seems to be throwing an exception when trying to render the firework rocket, which also could be a compatibility issue with rubidium's renderer.

Nevermind. This seems to be an issue with shield expansion specifically.
