BUG FIX:
We were made aware of a bug where people were losing all of their unlocked sex positions. We got to the bottom of it and fixed it. So you should now never lose the sex positions you have unlocked.
NEW FEATURE:
While we were doing this, we decided to also implement an idea that was given to us by someone in the Community. Before now, in cinematic sex you could only do the sex position you had just unlocked, but someone said, "why not all of our unlocked sex positions?" We thought about that, and decided it was a good idea. We couldn't put it everywhere, but where we could, you can now cycle through your unlocked sex positions while having sex with girls at the end of missions.
