[Abbey's Acres]

Love the new navigation tools for the co-op quests. But I have a problem - I have one farm with 800 horses on it (but not much else). Do I lose all horses in excess of the new limit of 400? This is a small farm 14x14 with only barns & persimmon trees besides the horses. I did this intentionally since I cannot afford to pay FC for a sufficient number of stables. I was aware it would load slower than other farms so I planned it in such a way that I would only need to visit that farm once a day. Did half of my horses just vanish?
