I recently got a PS3 and i got Crysis 3 one thing I noticed my internet stays online yet I get like kicked from games often when I am doing great.

One example this morning I was on a 13 kill spree (highest so far) going 13/0 with 2 triple kills and then the game ends I only have 2 hours into game so far so 13 kills is a lot for a weapon now I have to redo this. Is there anything I can do or is it like the host leaving game?
