My Team Bug

I have entered year three in my team where I have researched a part in aerodynamics. I was able to develop one of the parts but trying to develop the second one instantly crashes my game no matter how many times I try. I can do other things like research new parts, facility improvements, customize my car and gear, as well as advance. However nothing I have done has let me develop that second part with out them game crashing when I go to pay for the development.
