Track IR causes game to hang if it loses site of tracking for too long

[xaoslaad]

My friends and I have experienced an issue when playing Coop where the game hangs if the TIR camera loses track of the clip for too long. It doesn't take very long, my guess is somewhere between 30 seconds to 1 minute.

 

Has anyone else experienced this? Is it a known issue? I didn't see anything when doing a search of the forums.
