court of stars TW with a hunter that was level 87, who was at 484K XP at 548K XP, the dungeon journal shows 114K XP reward. i also have the 25% XP bonus
my player got nothing at the end and did not level to 88, only xp i earned was from mobs and bosses
i suspected this was going on on a previous run where this dungeon cycled, but at that time i wasn’t sure. so i wrote down the numbers at the start next time it came up.
