my game is seriously bugged, plz help

[marcmy]

Maybe not a mod problem, though I did install a few mods recently, they are:

 

HD Reworked Project

Map quest objectives Full

No dirty lens effect

Turbolighting

 

The issue I'm having is monsters are constantly running away from me, I have to literally chase them down, if I manage to stop them, they'll turn around and attack and then just keep going, up till a certain point where they will stop and attack as normal. My thinking is these monsters are out of place and when they see me they retreat back to their "home". But this is happening so frequently in so many different places the past few days, it just doesn't seem normal and I wonder if it's caused by a mod. However I removed the mods and the issue remains.

 

I also just came across a quest "A Surprise Inheritance" which has me going to a cellar in some ruins, but the door won't open. Clearly bugged.

 

Any ideas? Thanks in advance.
