[quote]but force abilities still worked on them.[/quote] The wiki is quite clear that the only methods that work are indirect methods, along with force lightning or force net. In other words, using force on a separate object and then using the object against them however you see fit, or using things with actual physical consequences outside of an all permeating concept. IE - They don't have a requisite to be connected via the force for these to work. It's also quite clear about them being stripped form the force after the destruction of their world.
