Entities Not Fighting!

So I’ve been playing around for a few hours on my new game, and have noticed a rather peculiar bug.
Randomly Players and Monsters stop fighting and kind of just either sit their as though they’re having a conversation or the Players run away whilst the Monsters chase them all the way to the exit of the Region. Now I used to have this problem with PvP Duels, as a duel would be initiated but no one would fight and thus the duel would never end. That I would like to say has been “fixed” however I find that when a duel is finished those same two Players sometimes just go straight back into having a duel, which is rather annoying.

Maybe it’s some weird code?
