Odd bug that I can't reproduce. I choose SO6X, on the BF1 and start my lap. I get a false start of 30 seconds and do a whole lap with that (never going below 100FPS BTW, So nice work there). I get to the end of the lap and Ctrl + S, spectate. I then do not have my skin (The default BF1 skin of the BMW Sauber race car) is no longer there. I load back into the race, inside the cockpit I see the inside of the skin, outside of the cockpit, I change view to the race TV camera, and I don't have a skin it's just white. I Ctrl + S again, and the skin is back.
Tried to reproduce this, and I can't. Might of been a fluke.
