Hello, I have purchased the endurance pack and have a concern. I was trying to set up a multi car race, but when the yellow loading bar gets approximately 80% done, I receive errors. If I choose the corvette listed as my car, and then I choose Porsche or DPI as my opponents I receive the errors listed. If I choose Corvette and my opponents are also Corvette, then it loads. If I choose Corvette and the Norma NM30 as my opponents, I receive a bone 02 NM30 error. Basically I cannot seem to choose multiple cars from the pack to race on the track at the same time. The AI has to have the same car I do or I get the errors listed.
