Got this from Operationsports. Huge discussion going on over there, this is serious. Some of you may have lost games or gave up TD's/Yrds because of this.

Updates:
Short summary: There is a bug in M13 where the CPU randomly makes your CBs run commit. This happens 5-10 times per game. If the CPU passes on these plays it usually results in a TD since the CPU WRs have a huge head start. Sliders cannot fix the bug. The only known workaround it to pass commit on every play.
Long version:
There is a HUGE man coverage bug in Madden 13 that is ruining the experience. Every 5 or 6 pass plays all of my CBs take 3-4 steps toward the QB before retreating and trying to catch up to the now wide open WR. This results in 2-4 easy TDs for the CPU per game. When this bug happens all of my CBs synchronize and run toward the QB at the same time.
I am seeing this on the Season Ticket version of the game. I am not telling the CBs to do anything different such as press, play run, etc. I simply call man coverage and they act like morons. It happens to all of my CBs, even high rated players like Champ Bailey.
Edit #1: This happens on normal pass plays, not on PA passes.
I have played with the pass reaction sliders and it does NOT resolve the issue. I have tried every difficulty and I even deleted the game and re-downloaded it.
Here is a video where my two CBs run toward the QB and leave both CPU WRs wide open. It isn't even halftime in this game and the CPU already has 3 TD passes due to this bug.
Edit #2:
I have been doing some more testing and I am 99% certain that the computer somehow tells your team to commit to the run. When I manually make the pre-snap commit to run adjustment my CBs do the same animation.
In summary, the CPU commandeers control your CBs and makes them aggressively jump the run. If the CPU passes on that play you are screwed. The only work around is to tell your team to play the pass on every down. Obviously, the downside is it's very hard to stop the CPU run game when your whole team is playing the pass.
In my opinion the game is unplayable until EA fixes this. How did they miss such a glaring bug?

Updates:
Update: Thanks to OS member Kiddlex, it appears that we have a temporary solution: controlling a player on the D-Line prior to the snap triggers the bug. If you control a LB or someone in the secondary the bug should go away. Once the ball is snapped you can switch to a DE or DT w/o triggering the bug.
Update #2 (info from PM sent to me from EA Sports Community Manager EmmdotFrisk)
It appears that the bug is triggered by pressing down on the RS immediately after the snap, regardless of your position. Because "user jump snap" has been removed, there could be an issue that is triggering run commit with right stick only.
