[Anon] Black Orcs (1b): equipment doesn't add cost to model

**Problem:**
equipment doesn't add cost to model

**Expected:**
equipment subtracts gc from total

**Additional Info:**
this is happening for a bunch of warbands

**List:** https://www.newrecruit.eu/app/list/7RhaB
**NewRecruit Version:** 34.45
**Platform:** Web
**Language:** en
**User Agent:** Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/146.0.0.0 Mobile Safari/537.36

No repository file or test is named. Start by opening the linked NewRecruit list and comparing its equipment entries with other affected warbands; trace where equipment costs are represented in the repository. Done means equipment consistently subtracts its gc cost from the model total across the affected warbands.
