I'm still having this issue. It's been happening since the new update. My driver is invisible when in game. He also fails to show up when I'm selecting my kart. I have triple checked to make sure the "Hide Driver" option is NOT ticked so it isn't that. Any ideas?
I had a similar problem, when first installing beta 2, but in my case it was the other way round, the driver was there, but the kart was missing. I coul fix it, by deleting the old kart files from beta 1, that were still in my Karts folder, perhaps you have the same problem with the driver 8)
I'll try that, thanks. :)
