Hm, that's weird. What other mods do you have? I've just tested with full bobs and angels and there were no issues. Are you using any of the shiny mods or some other mod that might affect.. whatever that graphic is? Does the error still occur if you disable reverse factory?
Try removing ShinyBobGFX. I get the feeling that Factorio changed something again and broke shiny mods. But then again, the graphics appears to be referencing something from angels, and you don't have ShinyAngelGFX, so I'm not sure...
Maybe you need both shiny mods if you're using both bobs and angels?
