it happened to me too, still does.... , after 71 points spent i can't spend another point even after i click commit, it happened to my boons point too, i already submitted my tickets n waiting. Then i realized about another bug, my dragon sigil point stuck at 10 no matter how much i got...... Very sad....
well it's not exactly the same, but my point power can't be spend after lvl 70, my boons point can't be spent too, at my dragon sigil stuck at 10 no matter how much i earned
