Nope, if I remember correctly I just bower installed all the core and paper elements but I have two different versions of it and my project used (imported) elements from both versions (not duplicates but different elements). The error resolved when I changed all the import paths to the same version of the core and paper elements.
I took a detour from this after quick fixing but I should probably do what @artem suggested here http://stackoverflow.com/questions/26766181/please-help-me-understand-this-error. Any other ideas are welcome as well, I will eventually get back to this. Thank you very much.
