New Harlem is suffers from real bad lag. I dont know if this is the building or the large mobs. Another problem trying to do the 5 pound workout missions the mobs are spawning in side the building. So big clusters of mobs are spawning in side a building and cant get killed. So you (slowy) running round buildings trying to find the red dots, but they are all in side.

You might want to consider to put a turrent at muscle beach. So new players can get their missions.
