I _think_ I got it working. In theory, after reboot, if you are mounted and
the mud crashes, your mount should restore when you return to the game. Your
mount's eq should come with it, but not stuff in saddlebags. How you get your
horse out of your chest room is up to you.
Naturally, let me know if it works/doesn't work/bugs in other funny ways. I am
quite interested in any "infinite horse" bugs.
