I like how some of the comments about the line being invisible are being down-rated while others are being up-rated. Yes, the line is invisible (permanently for some and temporarily for others) for some people. And no, just because the glitch doesn't show up for you doesn't mean it doesn't show up for others. This game is pretty much unplayable for me and I would really appreciate it if the glitch was fixed so that people experiencing this could actually try out the game.
Auto-joining is broken...
This is the only easy badge standing in my way, and the other badges are also there to consider. No workarounds have worked either. I hate to say it, but this game probably needs a removal.
It's fun to get a huge 5-star hotel, then destroy all the elevators and receptions to strand them all on high floors ;). They start running in the same direction after you delete everything. Somehow, I lost like 30 people (must have jumped out the windows).
