In no particular order;
Spell effects missing (like no beams)
Beam effects missing on world objects
Horse stays sprinting when stamina runs out (I don't mind this one but it's broke)
Spell animations stick causing your character to become locked and move really slow.
Interaction icon disappears so you cannot interact with doors, switches, npc's, chests, etc. Really annoying trying to hand quests in or not being able to get out of the keep door in Cyrodiil.
Apart from the horse sprint bug all these other bugs need a relog to cure it. It's getting somewhat annoying. I know I is a big patch, however this game still feels like it's in early beta. You devs need to step up a gear and fix these problems.
