This extension does a great job with updating the monaco_2019 and monaco_gp21 tracks to how the real track looks in 2022.
There are some minor bits that carry over from the original mods that shouldn't, such as the bollard at the T1 apex and some curbs missing UBS sponsorship. Granted that things like these might not be able to be fixed (I know nothing about extension modding lol), and that they would likely go unnoticed unless one directly compares the race feed to the extension. It's no biggie, but I figured to bring it up in case a v1.1 is in the works!
Overall, this update to the Monaco track is very faithful to the real deal, and Pyyer did an awesome job bringing forth the new changes to the 2019/2021 mod.
