I have at least four different final coalition scores (from the individual “ending event” screens) , all players have the same individual score as five minutes before the event ended. Around 50% of the coalition received the rewards for the second place, the other half for third place.
How?
/edit :
I might have posted this in the wrong subforum, would you mind fixing this @brigby or @bken?
RotGP seems to continue changing the leaderboard after it ends, including points people gained in battles that end after the boss is killed. That means what position people get rewarded for their coalition can change depending on how soon after the event end they get the reward.
