I was gardening at my house today. When I started gardening, by clicking the garden button, I was taken off my white horse, as is normal. A friend ported to my house and turned on my Zeke's Scavenger hunt. I was in the middle of gardening when the game turned me into a Sherlock Bones, also an action that seems to dismount a wizard. When the hunt ended, I was still dismounted. I checked my backpack to remount, but my horse was not there. I checked my backpack, bank, shared bank, and attic several times but there was no sign of my horse. A different mount that I had stored in my backpack was still there. I tried the place housing item button. In the housing tray with my pets and other mount was the missing horse. It's picture was shaded. I was able to select both pets and the other mount to place in my house, but not my horse. I ported to my dorm and tried to place my horse in the dorm. It's picture was no longer shaded. I was able to put it in the dorm and pick it up again. My horse was back and I was able to equip it again and see it listed in my pack. It seemed to me like this is a bug related to gardening and house games being active at the same time. If this happens to anyone else, I hope this helps you find your mount. Even more so I hope K I smooths out this issue. I was worried my horse was gone, and worse, I feared other mounts could be lost this way if I equiped them and it happened again.
