chandelier stuck

[nemesis567]

You're applying an impulse with the strenght vector of 0,0,0.9z. You should check if the lenght and mass of the chandelier is good enough to support that impulse without bugs. A way to know if the problem comes from some thign related to that is to reduce the impulse. If the problem is something else, you should check if there is the possibilitie that any of the chandelier bodies get's stuck inside somewhere. Like if it is stuck into the wall or something. If you just want to shake the chandelier(is it the roof one?) you should use an impulse in any xOy related direction to avoid any problems with the ceiling collisions.
