Fantastic! Sorry I just noticed it was the Modern Int. and not the Modern Office, I own both so please feel free to select the right pack for the trading desks/screens etc. that you think they belong. :) Keep up the great work! Also looking forward to the Modern externals/city when it becomes available.
