Duplicate DC every time I try to make a weapon in the Mos in Leafre

Hello, every time I try to make a Shiner Bow in Mos, I am disconnected from the game. This occurs in all channels and go back to the login screen like this:

 

That would be because you don't have all the required items to make the equip.
Maybe missing inventory space as well.

 

No. I had all the items and inventory space.
I took DC after clicking YES to make the bow.

 

Do you have enough mesos?

 

Yes, i have. '-'
I've done 50 bow, however, take all DC did that made one.

 

If you can provide a video/screenshots of it that would be helpful.
The NPC doesn't just stop working, so this is very strange.
