I find the belt fed LMGs (M60, MK46, PKP) go into the reloading animation whenever the square (use/reload) button is used.  This is of course the button for reload anyway, but I have been having my LMG go into a reload animation sequence whenever I try to pick up equipment, pick up care packages or detonate CR (double tap square). 

Example: With a full magazine and no rounds fired, I can deploy a piece of equipment like a trophy system.  When I try to pick that equipment up, it picks up, but the reload animation sequence begins.  This is a completely full magazine.  On no other gun type does this happen to me.

Does anybody else have this problem, or is it just me?

(Also find myself being stuck to the ground after spawning occasionally, with the only way to move being "jumping" out of my spawn point.  That can be for another discussion...)
