I was wondering why when you BUNDLE 250 grain it does not go into the same inventory slot? When I age cheese the new cheese replaces the old cheese, but when I bundle grain it moves it to an empty slot, or worst case scenario on the floor if all my slots are full. I just don't understand why it can't just replace the grain. The same goes for when you UNBUNDLE.
This seems like it might just be a simple "order of operations" error such as creating the new item BEFORE destroying the old one. Could be a quick fix.
