I'm doing Myst with this and like OnlyInDreams, it got choked at 55 at the Mass Sleep spell. I did some digging and for one, found that "ZGB" is listed twice for the mount types (not a biggie), but the other thing that appears to have happened is that the id for my horse is not what the script finds. So after a few tests, I discovered that if I put "G_2" at the end of the finditem line in the "GetHorseTarget" sub, the horse is found with no problems. Then I removed the g_2 addition and it failed, changed it to c_2 and it failed, changed it back to g_2 and it worked.
I figure that a radius of 2 would be sufficient being that the your script dismounts, so the search need not be large, but you can choose whatever.
This is at least the 3rd time I've used this script for different skills and chars, and I love it !
Keep up the good work
