Hello to all. I did a search, but it never works out for me. I must be doing something wrong. My apologies if this topic has been covered. I am sure it has. Anyway, I was at Practice 1 at Catalunya, and did the R & D and passed the testing. Well I wanted a new engine, and I know you have to make sure you run out all the time in the practice session or else you will not receive the upgrade. I kept thinking....I have a bad feeling that if I change engines now, after I passed the R&D that even though all of the practice time will be forfeited, for some reason I said to myself, I bet I will not be awarded the upgrade, even though I can see no valid reason what so ever that I will be denied the upgrade, but sure as heck.......yep, no upgrade! I knew it, and did it anyway, BUT it should have given me the upgrade, correct? Lesson learned...... don't change engines on a R&D session, even though there is no reason you should not be able to., that I can think of anyway. I thought maybe it will be in the next practice at the next race (Monaco) NOPE. Is this a bug or is the game correct? Thanks. . P.S. I just noticed a little mark on my avatar, and when I hovered the cursor over it, a message said"you have posted two messages in this thread", which is true. I am assuming this is a "no-no"? Sorry, it makes sense if that is the case.
