Was just doing a race and I pit to try fit new medium, as you can see in the MFD it says NEW, however to my surprise I get given used tires instead.
I 100% had new mediums, as when I pit again I got given them (for reference, you can find this moment on youtube, in the console social race at Abu Dhabi from World Online Racing)
As a result this ruined my race a bit, and I hope this is fixed as no one else should be experiencing this
