Steps:
1. I clicked on the Desynthesis skill on my hotbar, and it opened the window
2. I used the food item HQ Bacon Broth and HQ Tinker's Calm, which add buffs
3. I used the Desynthesis skill on many 690 furniture such as the Kitchen Cabinet, the Tea Caddy Cabinet, and Wall Cabinet
4. Carpenter Desynthesis Skill does not change at all despite my using the Goldsmith, Weaver, and Armorer Desynthesis skills on different items, and it does increase points.
