Issues with NPC's being far too fast and getting too close

I play in the current release version of B&S with the only mod installed the Medieval Megapack, but for a few versions i've found that NPC's are both moving and attacking at nearly unreactable speeds and zooming across the map far faster than it looks like they should be and then i remember them moving in older versions. I'm also finding it a consistent issue that multiple enemies will just blob up around be so close to each other that they're clipping into each other and literally are running into me making the game incredibly unfun as it feels more like a moshpit than a fight.

Is this issue related to MMP, is the game just gotten alot faster since the early versions I was more adjusted too? Does anybody have a fix or mod that can make things easier.
