[KoTOR] Cannot Upgrade Ranged Weapons

[milestails]

I started a new KoTOR game recently, and despite having several scopes, hair triggers etc., I cannot upgrade any ranged weapons. The upgrade screen shows me having zero of every upgrade at multiple workbenches. Currently, I am on Taris.

 

This does not affect my ability to upgrade armor and melee weapons (not sure about lightsabers).

 

Some mods I have installed:

 

WoTOR (w/patches)

Duros Merchant by MasterWaffle (comes with an upgrade.2da, doesn't use TSL patcher, and I installed prior to WoTOR)

K1 Restoration Demo

My mistake.

 

The issue was caused by the upgrade.2da file in the Verpine Implant Integration Visor mod not the Duros Merchant.
