It looks like you're changing stuff so maybe it's only temporary but you can only buy one property at a time right now. I hope this is not intentional because that would kill this game.
Indeed, what kind of BS move is this? I'm sincerely hoping it's just a bug/glitch and not a permanent change. That would suck mightily.
Take it easy people, this was almost obviously a bug. Give them a chance to respond before getting all worked up! Thanks for fixing this Kano.
