Speed up/slow down bug
 

I was playing chapter 2, doing really fast melee combo attacks. I noticed that afterwards my first person character was doing everything really fast, reloading the rifle in one second.

At one point I died with a grenade/explosive barrel. After the game loaded my save, everything was stuck in slow time, not like a performance thing, but like when you start using adrenaline.

This happened for my previous autosaves as well. I tried restarting the computer but nothing happened.

Help please :(

Oh, fixed the problem by restarting the level.
