Steps:
1. Accept the Weaver leve "Hanging by a Thread" from the local leve NPC "Eustace" in the Ul'dah Adventurers Guild.
2. Start Synthesis using the "Requested Items" menu from the synthesis menu.
3. Attempt the complete the leve using all materials available from it. Notice on each successful synthesis completion the game says (1 out of 48 threads completed).
4. Leve results in a failure due to unable to make all the items required by the client. The client expects 48 linen thread to be created not 4.

The Journal states the you only need to make 4 threads and to deliever it to Mimina to successfully complete the leve. However, NPC Mimina is expecting 48 threads which to be delievered to her.

Other similar leves that involves mass production might also be affected by this bug due to crafting yields changes on patch 1.19. (I haven't tried the other mass production leves to confirm this issue on them.)
