Thanks! Your mods are awesome btw.

Thats the only error that pops up when attempting to start up factorio. I checked YI engines thread and it seems that 0.1.6 version works (with script.on edits), but when he added/changed some recipes for 0.1.7 that error comes up.

I'm getting a _boblibrary_/recipe-functions.lua:4 attempt to index field ' ? ' (a nil value).

Using Factorio version 0.12.12
bobassembly 12.6
bobconfig 12.1
bobelectronics 12.5
boblibrary 12.2
boblogistics 12.7
bobmining 12.3
bobmodules 12.8
bobores 12.6
bobplates 12.9
bobpower 12.6
bobtech 12.3 ...
