This happened yesterday but I forgot to upload it. I had this happen when I was defending in a siege, and all the attackers' cav? nobles? came through with their horses. Even after the rider died, if I hit fast-forward after getting downed, the horses would climb the ladders. Also I don't have a screencap because I was busy cheesing an outnumbered siege, but in this one the infantry climbing the ladders would get stuck on the roof of the hoardings because they just kept climbing up to there.This was all at Jogurys castle.
