Yes, I first came here because I heard this was the map that is used for the game. So I just came to play around - that's why I added the beach thing. However, as it is an open source and I imagine it is also used for serious projects, I adjusted it as it is. I live there and I added the 2 parks on the block and I tried to add a new building that was recently constructured on the corner of Virginio-Malnati vs Chemin du Vieux-Bureau. 
I am not sure if I added the things correctly, though. But I'm keen to support and adjust it to be correct. So if you have any suggestions, please let me know how to improve it :)
Thanks
