It seems whenever I play a multiplayer game and/or in a party with my friends sometimes I will get disconnected out of the party. I will start to lag in the game and then it will say each of my friends leaves the party then I will either disconnect from the game or I will catch back up and it will rejoin me to the party. Regardless of me staying in the game or not I will just end back up in the xbox live party.The whole process happens in like 10 to 15 seconds. I usually try to check my internet as it happens and it seems fine on my computer like nothing is wrong.
I will post the extra info in a sec, my browser wont let me copy and paste for some reason here.
