Skeleton function while seeming normal has bow pointing directly down but is still hitting the player

The skeleton model is pointing the bow directly down im useing no texture packs no mods and am on a new instalation this is not a world download it was generated in the new snapshot useing a random seed. ive also tryed reloading textures and it fixed for a second then snaped back down.

From what i see it is caused by hitting them, might have something to do with falling but im not sure, it happened acrost multiple worlds and i was useing a copper sword during the attempts but havent put enought time into testing other swords
