I tried to load this TMX and build some walls. But my body always goes through wall#13 and stick to the bottom side of wall#9

body = world.Create(100, 100, 20, 20);

foreach(var obj in map.ObjectGroups["Obstacles"].Objects) {
  walls.Add(world.Create((float)obj.X, (float)obj.Y, (float)obj.Width, (float)obj.Height));
