Throwing axes have "unknown" damage type and also can't be used as 1H weapons. (I assume they should have a melee mode like javelins and throwing knives)
Faces of dead characters (including the player) in arena combat (and possibly elsewhere) revert to some weird looking default model after death.
Some large trees in forest battles have no hitbox (you walk or swing a weapon through them)
There are quite a lot of clipping issues with capes and equipment worn on the back.
Horses can get stuck and glitch out on the wooden spikes in some arenas.
