Frequency: Every time an HQ synthesis occurs (reproduced High Quality Synthesis over 20 times)
Character Name: Sapphire
Race: MithraF
World: Valefor
Main Job: Dancer, Lv.99
Support Job: Thief
Area and Coordinates: Mhuara Goldsmithing Guild, G-8
Party or Solo: Solo
NPC Name: Celestina
Monster Name: N/A

Steps:
1)Obtain Signet.

2)Buy any kind of colored rock from the NPC Celestina from the goldsmithing guild in mhuara. Mostly tested with White and Black rocks.

3)Obtain 72 goldsmithing skill or higher (I have 70 Goldsmithing + Shaded spectacles + Goldsmith's Apron which gives me combined 72 skill).

4)Combine wind crystal with colored rocks until you get a 'High Quality' synthesis.

5)When the High Quality Synthesis visuals and sound effect occurs (roughly 35+% of the time at 72+ Skill), synthesis only yields light opals (in the case of white rocks) and onyx (for black rocks).
The expected and previously working behavior when carving colored rocks (skill cap 21 goldsmithing recipe) is to obtain one of 3 different high quality stones when an HQ synthesis occurs.
I have crafted thousands of stones over the years and up until a few weeks ago I have never seen this bug occur before. I would guess this bug was introduced in the last version update.

Other notes:

Logged character in and out, repeated high quality synthesis multiple times, changed zone and came back.

Tried many synthesis with and without the 'Craftmaster's ring' equipped (add 1% HQ rate chance) and was still unable to receive the proper HQ synthesis materials when the HQ crafting visual and sound effects signaled an HQ synthesis had occured.
