How is the "batch" function supposed to work? I assume it is supposed to check to see if you have the necessary items in your inventory to create 5 identical items. However it doesn't appear to function as I would expect.

Here I had 5 spear heads and five wooden poles. I could create them individually but not as a batch. Am I missing something?
I also encountered the Borcha problem with camping - He was removed from the party, but appeared inside the camp. If ambushing he rejoined, but otherwise he seems to vanish??? I've also encountered random crashes in the ambushes. Can anyone else verify this? I restarted the game to make sure it wasn't any of my equipment, borcha etc. that was causing the crashes, and I still experienced them.
Winter, may I ask why you like the identical inventories in the craftshops? It seems to be odd that craftsmen in different cities do not have different items in their inventories. If I go to shops in two different towns I naturally expect to find different items. I don't think online shopping was implemented yet in this time period
