Well, i'm sick and tired of buying the sheep farm, and someone else buying it before i even make any profit off it. Either make more high maintanence properties, or increase the time in which someone can steal it from you.
And another thing.. When someone buys out your property, make it a red text. Because when im buying shitloads of properties, combined with all the other yellow/orange text the server generates, it is very difficult to detect when my property gets bought out. Especially when i have a large number of them. Either make the text red, or have a small 2 second alert noise. The covert casual orange text is annoying.
