CC report https://github.com/chromiecraft/chromiecraft/issues/5116

### What client do you play on?

enGB

### Faction

Both

### Content Phase:

61-64

### Current Behaviour

Scryer JC trainer Kirembri Silvermane, and Aldor JC trainer Nemiha are also selling the wrath JC designs.

### Expected Blizzlike Behaviour

They are only supposed to have the [Jeweler's Kit] and [Simple Grinder] for sale.
Only Timothy Jones in Dalaran should have the lvl 80 epic JC designs in stock.

Start by locating the vendor inventory data for NPCs 88267 (Kirembri Silvermane) and 88256 (Nemiha), then compare it with the referenced Timothy Jones inventory. Confirm that the Shattrath vendors sell only Jeweler's Kit and Simple Grinder, while the level 80 epic designs remain with Timothy Jones, and verify both vendors in-game.
