Masteries

Strange thing happened to me in masteries…
I choose one, regen to replace potency, then i reroll it until i had 13.95% ( gold) i pressed confirm and bam 2 new masteries appeared so all gold and wisdom i spent for the previous one was lost??? and i has to start from scratch again!! 
Anyone had the same thing?

Result i lost a lot of gold and wisdom as my vaults are almost empty because of this, meaning no forgery for me and no gems for the next 2 days…

I also have the same problem like you, my money and wisdom lost because of it
