Game Bug or Mod Bug? Only happens when two specific mods are enabled.

[Kzisor]

Okay so here is my scenario; I have Additional Set Pieces enabled and whenever I enable a mod that I am currently working on which has modded items it causes this crash. It seems to be very random and can happen even with any mod that has a custom recipe.

I cannot determine if the cause is from Additional Set Pieces or if it's a Klei bug.

@Kzisor,

Does any of these items you are working on, get a MISSING NAME, when spawning?

 

You have the custom recipe for a prefab.

But you do not have the string name for a prefab.

 

If they do that's probably what's breaking this, since

STRINGS.NAMES[ITHASARECIPEBUTNOTANAME] = nil

@DarkXero, yup that is the problem. I am adding recipes but, not adding the strings as of yet. Thanks for letting me know the cause it's been bugging me for quite some time now.
