Bugged walking animation

Zombiesquidbily

While playing yesterday, I dismounted my horse and walked over to a material node then suddenly my player model went into the horse rider pose and scooted along the ground. I remained that way after jumping, picking up another material, running around, casting magic spells and ducking. Once I changed weapon hands it reverted back and didn't return. My character is a Templar High elf and it occurred in Eastmarch.
