Hi! I've just reviewed your game page and must say that your game is quite impressive-looking. I'm working on something similar myself although I am not that far in development yet and am still only offering to the F2P market. I've read in this forum about a hard-to-replicate bug that causes cars to be assigned to the wrong race finish positions, and have seen nothing here about this bug being fixed. I've also read in the changelogs that there's actually been some tentative fixes to address this specific bug, but I don't know if it got entirely rid of the bug or not, since I can't try the game myself at the moment. However, since I've had to deal with similar issues myself while working on my own game, I know for a fact that there could actually be several different little bugs all hidden under the guise of "one bug" only because they all lead to the same result, aka cars being placed in wrong positions. So, since this bug is hard to replicate to begin with, and replicating the bug is key to understand what's actually going on, I simply wanted to point out to you that there seems to be an instance of this bug showing in one of your screen captures, the one with the newspaper article about race results.
In it, it says that Jean Allegro won the race, which is confirmed by the rankings on the left side of the screen. Then, the article goes on to say that his teammate hasn't been so lucky and actually didn't finish the race. However, if we look at the rankings, we can see that Jean Allegro's teammate, Damien Cliffe, took his Stromboli car into 5th place, scoring 6 points. So, there's this bug in full display right here. Like I said, I don't know if this is still a relevant topic at this point in time, but if it is, I hope this little bit of info will help.
Hope to be able to try your game soon!
