Steps:
1.After you have raised the Craftsmanship rating on your shield to 100%, trade it to the guild master to be rewarded with a C. Crystal- Alch. icon.png Craftsman Crystal as in the previous phases.

Raising the craftsmanship ratie to 100% didn't provide me C.Crystal, i have R0 during the trading process.
Since that Disconnection, the npc say the same answer (like if i have cancel my shield upgrade)
