I always got an error when sending the items on Grand Company Delivery Missions on Provisioning. the ERROR I mean is I cannot sent it when the first one already sent.
I have two Gathering Class (Botanical and Fishing).
Example: When I completely sent the Botanical GCDM Provisioning mission, I cannot sent the Fishing one. and It has already happen 2 times in a row.
Please check if there any problem in it.
PS: I played in Japan Server
