all skeletons I spawn in are fine on most block's but when they move onto grass path they can sprint right up to me and end up going in circles around me extremely fast. it spears to only happen with skeletons and strays, not wither skeletons, and only on grass path. the skeletons could be from an egg, command or just naturally but as long as they are currently on a grass path they are very fast and broken. This is very easy to reproduce but it is most noticeable when you are springing away from the skeleton while on the grass path.
