Homeless Sims

[SockoJr53 51]

Well I was just booted for server maintenance (Standard Operation Procedure at this point) So I figured I would ask this here, I didn't see any search results about homeless Sims. I had a serious homeless problem, turns out I had an entire neighborhood of abandoned houses, there was a land value issue I had to correct. Once I cleaned up the neighborhood, the massive outpouring of homeless milled around the city for a while then settled in all my parks. Now the middle class is complaining that they don't have parks, since they are occupied by all these bums.

Is there anyway to truely get rid of these people? I have no more abandoned houses, and no more trash piling up. I read in the game that homeless will take the busses out of town if they can't find trash or abandoned buildings, but they just wont leave, they just sit in my parks all day. Did anyone else run into this problem?
