1) Arrows shot by archers and fire spells cast by mages appear to fly from the source to the target, but then another arrow/spell flies in horizontally from left to right, striking the target from out of nowhere. I think this might be carried over from beta 3.
2) The storm spell animation happens, but not on the target hit by the spell. For example, the lightning strike appears to hit a unit, but a diffferent unit two tiles over is the one that takes the damage.
