Oh boy! Had quite a scare tonight. It appears my Darcy Ranch save game got corrupted. Luckily, it would let me load long enough to save a copy of the updated Training Grounds I did to the library as well as a copy of the household with house as well as a copy of them without the house (just in case).
I then started a new Appaloosa Plains game, inserted the Darcy's as well as the Training Grounds and all appears well again. Phew! I think it was the training jumps on the ranch that got screwed up. When I tried using them on the new game, I was getting pathing errors from the horses (although nothing had moved). So I deleted them and put all new ones in and no problems with pathing. I would have been VERY upset to have lost it all.
Here's a little update. Alexander, the son, has matured into a young adult and is quite the competitor. Also, the daughter of an old family friend, Fiona Lathrop, has come to stay with them as she wants to learn more of the horse business. As a result, Alexander and Fiona are getting on like a house on fire and are now going steady. Alexander had already talked to his father about buying the empty piece of land next door and building a house of his own. So he's saving all of his winnings toward that goal. In preparation for that time, they've added a second stallion to the ranch. Alexander is working with him every day. Fitzwilliam has given Alexa to Alexander as well so he'll have a stallion and mare to get started.
I've got a nice idea for the house that I'll build as well. Am looking forward to it!
