Hi,
I couldn’t find a similar post…
When ever I apply a custom colour scheme with decals or when I download a design from someone
else they rarely remain in place on the car in ‘‘my garage’’ or in race. Meaning that as soon as I boot the
game back up the design for example on race cars, show a glitchy grey version of the original colour scheme
or in case of the Audi R8 GT3 car a pink and green glitchy colourscheme.
Also the tiles in the selection menu of my garage often show the incorrect colour or design that is exactly
applied to the car.
The my garage function is extremely laggy and slow (I play on a Xbox one X), while the buy a car menu works
absolutely fine.
I hope someone can shed some light on this or if others also have this problem, so far I must say this is by far
te buggiest forza I’ve played 
or as trump would tweet: SAD!
