Odd Error; Null Ref

[TehAgent]

When I click on two specific items, it throws red errors. I can hit esc and click off it it onto something else and make the console go away...but I can NOT click on these items in my backpack or in a crate without the error happening. So far its only happening with brass knuckles (which I havent touched) and the impact driver, which I did touch - but all i did was change the repair item.

Heres the log entry:

I have no idea why it started doing this. I havent messed with any of these XUi ; Im not even sure where exactly to find them.

EDIT: Something I did definitely messed up the driver - I reverted it from using a tool battery to 'repair' to a different repair kit, and it is fine now. Something must be wrong with the battery itself...but whatever. It wasnt going to work properly anyway. I wanted to make the player charge batteries but it was a lot of annoying 'stuff' to take a battery out and replace it.

If you set an item as a repair item for something but that item doesnt have the RepairAmount and I think RepairTime is also required, it will error. You can look at things like resourceWood to see them.

Aha...thank you!

I did not add repair amount or time. I bet I did touch those knuckles early on when I started this Mod project. I was making things a little more 'realistic' and I bet I made it repair with brass or something.
