Seems like you had a chicken outside of the screen. The animals now die if they are loaded outside the base.
I haven't noticed any campmate amount changes. The base value changed by 1 when I tested it. I'll test some more though.
Your base is stressing my work computer (not very good PC) pretty heavily (how many farms do you have!?). What is your frame rate on your computer in the base? Anyway I'll probably use your base as a stress test and see if I can improve performance.
