Splitscreen Bug I've Noticed

I apologize if this was mentioned before, but I would like to mention an annoying bug I have noticed during Splitscreen action.

-Whenever my buddy or I either bring up the Skills UI or die, it causes the other player to stop firing, or in the Sniper's case, bump out of the 1st person view when zoomed in.

So many kill opportunities lost and so many unnecessary deaths obtained. :/
