Had to turn my mods off one at a time until Rampant Industry loaded, it was Disco Science lol. Not the end of the world I'd rather have industries than disco science, but rip my beautiful science labs.

I don't use disco science because of the ups hit.
What was the error you were getting?

I had disco science as well and this is the error that popped up. don't know if this is what you were meaning by it though.

Failed to load mods: RampantIndustry/prototypes/Buildings.lua:98 attempt to index field '?' (a nil Value)
stack traceback:
RampantIndustry/prototypes/Buildings.lua:98: in function 'enable'
RampantIndustry/data.lua:19: in main chunk

This is a low priority for me, but I will add it to the todo list.
