Double skillpoints on level up (exploit)

Hello,

I found this potential exploit today while leveling up. I selected a skill on the passive tree, then deselected it and clicked it again. It now gave me the refund skillpoints option (but I was not talkig to the hooded one). I accepted the refund, and it didnt disappear, but I now had another skillpoint to spend after pressing "cancel refund". I wasnt able to duplicate it, so that's good at least. I'll update thread if I can duplicate it again on next level up.

I tried refunding apoint at the hooded one and do the double click again while selecting a skill, but that didn't work.
