Progress ?s

Hey guys, I just wanted to say that I bought the stand alone version of the game and I am loving the dev tools that I have access to, but I had some questions. In the 1.4 build of the game I had a whole bunch of content that I made that got deleted with the 1.5 build update on the 28th. Wondering if that is going to happen to me again or, if it is how should I back up my data? Secondly with the content I make in the sandbox portion of the game am I going to be able to access my cars and engines in the tycoon mode from what I built in the sandbox? Also could we have the option of saving the engines/cars we build in the senario mode? Lastly I am extremely interested in when we may gain access to more engine and aspiration types? You all are doing an amazing job and I am not trying to rush, just looking for a ballpark time frame for single turbo V configurations, V6s, and superchargers. Keep doing the amazing job you are.
