Ok so we got a new update, and a free copy of Shan Shui card from shop!
When claming this card we are presented with the option to reroll (dust value +400)
I have the entire Karazhan collection…
But when i re-rolled in my case (barnes) It only says that i got only 1 copy of it in collection (and +0 added dust.)
This means that by clicking on re-roll instead of keeping the card i got robbed of 400 dust.
