Do you have any details on the update in July?

So I have been wanting to build a base or car or something. But my question is this. How often do the servers restart? And when they do is EVERYTHING wiped out? Because I was told by someone that if you start to build something or whatever you doing it will be there for 45 days. Is this even remotely true? Or do you literally have to do all your stuff before the reset and after that you just gotta start over? Any answers would be grateful
