Something wrong with saving in Forza 3 on PC

My Forza 2 save got wiped somehow, it was something like i was level 1 after being 40, but then i could do like endurance races or something, and then my forza 3 save went the same way

I have the same issue, but then between an Xbox Series S and my pc. There seems to be something wrong with the pc not detecting whether the saves have synced properly.

Yes,i worded it wrong...

what i meant was there was several unicorns in forza 3 in the vip pack ,that are also unicorns in forza 4,so when you import your save file you basically have unicorns already ,and the achievement unlocks too.

I deleted/uninstalled both Forza 3 and Forza 4 from the console. On restarting Forza 3 (this was on Thursday 13th October) I was asked to accepted the title update - if I didn't I couldn't play the game). I have backed up and then deleted my Forza 4 saved
games and restarted from scratch - still no option to import from Forza 3.

It appears that what ever the title update on thursday 13th patched it essentially made the Forza 3 saved game unreadable by either Forza 3 or Forza 4.

I cannot continue the Season play in Forza 3 from where I last saved it as all the game progress appears to have gone. The achievements still show on my profile, but I cannot import into Forza 4 as it appears the title update delete all the data for Forza
4...

I read some article that xbox has the best copy for now. Ps3 with the save stacking lag and pc had something wrong with it, too. But we all have bugs, lol.
