Hi can anyone help? I am having a problem with creating my light sabre when I speak to Boa Dur about creating it he says I need a lens but I have 3 lenses in my inventory. I am on Dantooine. There also seems to be a problem using repair pack and spikes to fix the droids and computers it says there are none in my inventory. Does anyone know how to fix this? I have a save game where I went to went to another planet first and I could make my ligh sablre there
