After 7 patches and still no fix i wonder if anyone know some kind of workaround to solve this problem. Sometimes when the enginer says that the R&D has failed, i guess its a "feature" but when you complete the test and he doesn't tell you anything on the practice or qualy, im sure its the "Bugmasters R&D feature". On season 2 i had 2 upgrades that worked, after the second everytime i had and upgrade it was an R&D test and i didn't got any new part by the end of the season. Now first R&D with Lotus and no game, haven't even saved my game this time. So, if anyone knows how to avoid this problem, please, say it here!
