Reading the relevant code that seemed to cause this crash, it looks like you had some kind of rocket silo but without a recipe to actually make a rocket. I am wondering how on earth (or space) this is possible, are you playing with some specific mods that has a rocket silo without a recipe for the rocket??

Satisfactorio uses rocket silo different from vanilla

I have released version 1.1.2 of the mod now. It should most likely fix the issue but I have not done any testing whatsoever, so please verify that it works.
