Can play demo forever without purchasing

Hi, this might have been reported and/or fixed already, but I really did try to search the issue tracker and the release notes, I found no mention of this in either (maybe it was reported as private, I have no idea. Maybe I'm really the first to discover it). I can't reproduce it because I actually bought the game.

When I first started playing, I got the demo. I read all about what to expect when playing the demo; on launch the menu displays text about Play Demo World, etc., the world ends after 100 minutes, and so on. But none of that happened. I was able to create new worlds, play for much more than 100 minutes, and nothing looked like demo mode when playing Single Player. When attempting Multiplayer, of course it didn't let me.

Anyway, I had planned to purchase the game anyway, I just wanted to make sure it ran on my older graphics card first, so as soon as I knew it worked I purchased and activated the game, so I have no way of knowing if this is fixed in 1.6.x (plus, like I said, I see nothing in the release notes or issue tracker). So anyway, that's what I experienced; hopefully that gives you enough information to work with. Thanks!!
