Not sure if you can call it a bug but when you don't click the ability redistribution button when the dialog appears and instead you leave the map (because ability redistribution around etins might be hurtful) or probably you get disconnected (not tested) you lose the chance to redistribute the ability points for free since the dialog just closes.
On a side note: the ability redistribution item in the mall costs 3k RE but 10million crit check 330 RE, since ability redistribution lvl > 50 costs 50 million you can get it cheaper with crit for 1650 RE buying 5x10million crit. Now if the ability redistribution item works for dual classes it might be worth the 3k, otherwise I would suggest to lower the price for the ability redistribution item and maybe rise the 10million crit one a little to make them about equal. Rising the crit price for higher lvl redistribution might also be a solution but at some level people will rather wait for level 101 than spending more money I assume
