Hi, I'm playing the 3.6 beta version on Steam and after the drying period there are more cords than there should be for the amount of prepared meat, based on the quantity I believe all the cords that were used to dry meat in that tile became available after the first batch was completed, to confirm this I will keep playing until the next batch is done and then update this post.
Indeed my guess was correct, after the next set of meat was done the amount of dried meat in the the tile increased but not the number of cords.
