i just encountered something really freaky

in act 2, where the first time u get to "push a car" towards the troika machine gun

this is what i did

i pushed the car into the middle, not to the end. (there is a square brick on the right ) then i stopped. i killed the troika from this position.

advanced and killed all the goons and locusts.

once that scene is done, i turned around and looked at the car
the car was floating around like a seeder!

it was bouncing and floating and spinning back to its original location

its so freaky and weird =.=

dunno if it will happen again for others or not
