Is anyone getting corrupted data on tunes and game crashes by such?

I was wondering if anyone has run into the following situation… I have one specific car (for whatever reason - Mazda 787B) which I have downloaded other creators tunes, had a couple of open source tunes which I plugged in myself, as well as, I created 2 tunes for. Now every once in awhile, when I go into the load menu, my game crashes and it sends me to the original/main FM5 screen. I’ve tried this with many other cars and I have no issue. It seems that (from what I noticed) I primarily have this issue when the servers are down and/or having issues. The weird part, why just this car. Thus, is it a corrupted tune file? Has anyone seen this?

Should I delete al the tunes associated with this car (if I can get to menu)?

Thanks!
