Sponsors can be put on the Crescent livery with a minor exploit

So I have found out that with a minor exploit you can actually put sponsor decals on the FOM Car when using the Crescent livery despite the game saying that it isn't compatible with them. Here is how:
1: Select a livery that is compatible with sponsor decals.
2: Put the sponsors on.
3: Switch to Crescent and equip it.

In the main menu you won't see them on the car, however if you are in a race or in Photo Mode the sponsors will appear on the car (like on the picture above).
(NOTE: This trick doesn't work in My Team career mode.)
