ill copy some bugs i noticed that i posted in another thread
ive seen a parked car just sitting on its front two wheels, with the back ones a metre in the air, i walked into and the back wheels fell to the ground.
i had a cop car dissapear that was right in front of me, and then fall from the sky and hit the ground right in front of me.
i slid sidways into a tree which sent my car a couple in the metres (about 15 metres) in the air as it got caught between the tree and a fence
if you park your car between two things (a wall and a tree for example) and it blocks both of the front doors, try to get out and see what happens. the car suddenly flips on its side and niko then climbs out the door.
similar to the bug above, if you try to steal a car from the passanger side when the driver side door is blocked (from a car or something), the driver will suddenly appear outside the car as soon as you get in
(in reference to the new cover system) sometimes, if your in the right spot, and you try to cling to a wall, he will actually cling to a different wall anywhere within 10 metres around you, for example. i was standing at the top of a flight of stairs and wanted to cling to the railing at the very top of the stairs, so i pressed RB, and niko ran (faster than he can actually run in the game) to the bottom of the stairs and clinged to the railing there. ive totally given up on this new feature and just end up crouching behind something.
