Horse Disappears After Death and Sheep, Goats, And Chickens Disappear randomly.

I recently lost a horse, but there was no notification or gravestone for its death. The Grim Reaper didn't even reap the horse; it disappeared while sleeping, and my sims gained the 'Mourning Horse' moodlet. My chickens, goats, and, sheep are randomly disappearing as well I didn't receive any notification warning me they were going to run away they just disappeared. I had never had this problem until I played on the lot Canter Cottage in Chestnut Ridge. I played with the same household before but on a different lot same world and I didn't have these problems.
