Saber disappears after using workbench

[Circa]

I'm a bit rusty when it comes to KOTOR modding, but I haven't seen this happen. I added a saber as a new item (not replacing the existing ones) and it works fine, but I can't upgrade it. When I go to the workbench, I select the saber, and it disappears from the workbench and my inventory completely. I haven't found any threads about this. Is that normal or am I missing something?

I think you have to add the saber to upcrystals.2da for it to be upgradeable.

Ah, you are correct. I added my saber to the list and pointed one of the existing color crystals to it and it appears to have worked. Thanks!

Glad to hear it did. 

Be careful with reusing an existing crystal however. 

If you do that and at some point take the crystal out of the saber you won't be able to get your saber back. That's because when you put the crystal back in, the game will check upcrystals.2da for the first row with this crystal and give you the corresponding saber which would be one of the standard sabers. 

If that's no issue for you and you don't want to release it as a mod you're fine of course. 

Otherwise I'd recommend creating a new crystal item and also short and double blade versions of your saber.
