Since the latest build has been released I've seen multiple instances of drivers joining our MP servers with the Corvette Pace Car. Visually I can see the correct model we are hosting but you can hear the Corvette engine sound and their car model shows as Unknown. It's not contained to one specific mod, I've seen it happen on several different servers running different mods, I've even had it happen to me at least once on our Dallara server. I also noticed when this happens the car looks like it floating around the track, this could be related to tire size of the model it's supposed to be, I'm not positive that visual clue happens with all models, we were in the Brabham. So far, having the driver leave and return fixes the issue but this needs to be looked at and fixed asap. Even Liveracers reports these occurrences as Unknown or Pace Car..
This is an old bug and has happened also whit ISI and all other servers. http://isiforums.net/f/showthread.p...util-or-plugin?p=387898&viewfull=1#post387898
