Mount Bug

Whenever I equip my Mount, the initial animation has my Character sinking into the Mount, and it only comes back up after the animation is completed. This occurs with all Non-Horse Mounts. Further, my Armor Enchantment and augment Ioun Stone companion disappear on mounting and remain so even when I dismount at times.

As a side note, why does the Svardborg Conqueror's Banner not show up when mounted- it does not interfere with game physics unlike the capes. It would be neat to have this item visible when mounted.

Thanks for your efforts.
