(i'm playing with a lot of mods)

Failed to load mods: Error while running setup for prototype "small-lamp" (recipe):duplicate item ingredients are not allowed (glass exists 2 or more times).

don't know whats the issue (not gonna blame the 200+ mods on) but this one was one of the issues

It's probably one of the Py mods. from other bug reports, he seems to just blindly add new ingredients to a recipe without checking if they exist first.
