When you roll back aai-industry to 0.3.5, or disable either angelsrefining or bobslogistics the game loads fine.

Have you reported this to Angel?

Someone's having a similar error on Angel's Bugs & FAQ.
Will post this over there as well.

It's probably something simple like an if statement needs to be added to 1 function.
