A recent update for Call of Duty: Modern Warfare made some odd changes to player collision where players were able to knock others into a line of sight, causing them to lose a gun fight or be unable to react.
Infinity Ward’s Joel Emslie has confirmed on Reddit that they are looking into the changes and investigating a fix for it. He said he was not 100% sure if the fix is in testing already or still being worked on.
We are definitely looking into that. Im not sure if the fix is in flight or still being worked on.
There’s no indication yet for when the next update for Modern Warfare will go live. Infinity Ward has mentioned that they are continuing to work on it.
