So I just quit Spartan Thorne because some loser who was running everyone over with the Ghost went to the back of the map to some part in the cliffs, and when everyone else respawned we would be stuck behind some invisible wall.
Amazing how an update just came out yet things like this can still happen. I had spent over 20 minutes in that game and now I'm forced to quit and have nothing to show for it.
Yes, you need to finish the level to use double XP, if you don't finish the level, it's not wasted. I had to do this several times in previous games where I would spawn in a rock when I died, and then when others died they'd spawn in the same place that I was. Waste of time, but didn't waste my double XP tokens.
The Princess is in another Castle. Punching trees gives me wood.
