For some reason if I try to change my horses diet it never works the first time.
Most of my horses I change the diet so I enter the new values and hit update. The page will reload but if you look at the diet it has switched back to the original default diet. In order to get it to stick with my changed diet I have to input the diet once again for a second time before hitting update and only now will the new changes actually register and replace the old diet.
Not sure if anyone else is having the same problem or not, but thought I would post this here as it is starting to become a pain XD
