I’m on the Open Beta build and I have access to my shiny new V16’s (awesome) but when I went to build a V10 in Tutorial D5 - Supercar I found I had no access to V10’s!!!
I’ll update if I find out anything further but hopefully you’ll be able to find 'em again soon!
EDIT: I made a V10, no problems, in the sandbox so the tutorial settings must need calibration!
Thanks again for the V16’s, they were worth the wait
