For Host:
Unfortunately to get your XP to stick for hosting. You cannot be in a party. What you do is host a lobby get the amount of Xp you want then back out. As soon as you see the multiplayer menu Sign Out. Then sign in. You will have stuck your XP to your account.
For Other People
If you want to have your XP to stick and you are not the host then you want to get the XP amount and wait till the host leaves. Once he has you leave. Your XP will be stuck.
Most people already knew this but I made this thread for the people that didn't.
You can be in a party for the xp to stick to the host , when you backout instead of backing out with party , click "No leave party" then when its switching host sign out then right after sign back in and the xp will stick for the host and the other players in the game.
