Are you kidding? There are bugs in the physics engine, like when you step on something small sometimes it goes flying across the room in a random direction, and there are a bunch of little corners that you can get stuck in and it takes a while of jumping and moving to get out. Plus, bodies often disappear (I noticed it more later on in the game) right after you kill them so you can't loot the items, as well as grenade/locked boxes and ammo on occasion.
They are not game breaking and the game is still awesome, but there is no denying that these glitches exist.
