I recently posted that mounts are not combat units. Since then, in two occasions, approaching hostile forts/dungeons with enemies outside the dungeon, my horse runs off and storms the castle. I'm stuck fighting a bunch of guys and next thing I know my horse is nowhere to be seen. When I got out of the first dungeon, I found Shadowmere dead on the road. Just got out of another dungeon where there was a fight to get in there... horse is no where to be seen. I fast travel back to Whiterun, go to the next location... no horse. I assume it was killed running off and attacking other hostiles. Had to buy yet another one. This is my 3rd horse. This is getting ridiculous. And the Shadowmere loss is extremely irretating as it was a nice looking horse that can't be replaced!!
Please!!! Do an update that prevents mounts from running off and attacking things!!!! Not only is it exceedingly annoying, I want to kill these things!! Not let my horse do all the work!!!
