I have been inputting births into the system, now having learned properly by going through the accounting side first. For my group under inputs it shows 14 animals, which is correct. When I go into Farmstock and I go to inventory with the group selected I count the 14 animals that should be in there. However when I go to inventory check it says there are 15 animals in that group and only 67 in the cow group which should actually have 68. What have I done wrong?
