There is a bug, or it might be coded in. You might not have the problem, you might have it. No matter, it seems whenever I have Jedi robes before the holo - be it Random loot, or more recently a mod I requested and play it with. - It seems to remove all of them from wherever they are, be it on characters or in the inventory. Note: These are the ones called Jedi Robes. Nothing else.
In the holo you see the Exile wearing Jedi Robes, for some reason it gives you a set of Jedi Robes and a Lightsaber during this, then removes them after it ends. But if you have either of these items already on you in any way, it removes all the Jedi Robes and one Lightsaber from you. Anyone got an idea what I'm on about. I would do a screen shot, but I know no way to do it without attachments.
This has nothing to do with Mods, I had this problem before I started using mods. Please help me, I'll give you a link to a mod for extra robes if you do.
Note: Those robes will replace all current ones with stats included. Not a bug, but intentional. If you ever had problems getting robes while LS.
