Unacceptable.
Do better
….Care to elaborate?
If you have a double xp booster on, and play a game of last spartan standing. When it tells you that you can leave the match- your challenges do not automatically update until that game has finished. However, when it does catch up/ update. Double XP is not applied to the completed challenge.
This is something I have observed also and filed a ticket for.
Not really.
Nothing is traking except spoils.
