A player riding on a horse, in front of a one block high wall. The player sprints, then attempts to go up wall. Sometimes, you get stuck right after you climb the block, making you unable to go forward. When it happens, sometimes the player and the horse takes damage (unsure how to duplicate this part, you might need consistently steep hill; however, there is no reason for either to take damage; might be due to bugged fall damage or suffocation).
