In my game of TSL Bao Dur asked if I wanted to build a lightsaber. I had the energy fixture and the emitter, but not the lens. After I defeated Visas it said I had a lens, but Bao Dur (and the journal entry) kept saying I was missing the lens. I bought salvage from Jorran and recieved a short lightsaber. My journal was updated and now it says Bao Dur has sucessfully helped me to build a lightsaber. When I talk to him, the lightsaber option isn't there.
I have the TSL Restored content mod and Force Fashion II installed on my game. I suspect they have something to do with the problem.
Huh, this sounds awfully strange. LoL. I think it could be a bug. Well the game seems to think that you have already built your saber. I would try and mess with it a bit. Sorry I couldn't be of more help.
I just encountered the bug. After several playthroughs trying to find a solution, I'm not sure if you wanted to install a new mod to fix this or not but the only way I was able to fix it was by installing the TSL HakPad mod which gives you the parts.
~ I know that you believe you understand what you think I said, but I'm not sure you realize that what you heard is not what I meant.
