1) This is a side-effect to the way that I made it so you don't automatically attack when using one of the NPC fighting styles. Since the sprint button is the attack button, you'd attack before running and that was annoying. So I disabled that and now you can't super sprint :/
2) Some peds are meant to fight, other's aren't. For example, Sheldon is a coward so recruiting him is probably no good. But if you recruit Russell, you better believe someone is gonna get smashed.
3) There isn't many mission glitches that I'm aware of, but there are a few. It should run smooth for the most part.
Glad you enjoyed it.
