if any of you find a useless glitch, post it here... I recently found one when I was doing a run (sorry its muted:()

http://www.twitch.tv/derek31037/c/5413422

the second set of ballas didn't spawn in the mission drive-by, so I had to fail the mission

All you have to do to get them to spawn is press look back after you kill the last guy of the first group..

I've found this one which removes the collision on the garage door and makes the collision detection inside the garage kinda bad(sorry for the shitty quality). This also works on Pay'n'Sprays

Another useless glitch is if you kill yourself when it's roughly 5 sec left of the hospital/police information boxes you get put into some sort of cutscene mode where the hud and mission markers are gone (you can still start a mission by walking where the marker is supposed to be and that will break the effect). I start this glitch be answering a phonecall when the information starts which gives me controll and then kill myself when it's 5 seconds left.

Here's the extended cutscene mode (video quality is bad)

And here's another useless glitch (answering the phone midair)
