Hello !
Just a tiny bug, not a game-killer, no big deal, but I still want to report it, when you hand over a crafted item regarding a voucher writ to Rolis Hlaalu, the reward screen display a number of zero to the amount of vouchers granted. Right after, in the bottom-right corner of the screen, the accurate number of vouchers is still displayed, though.
I have absolutely no idea about when this bug first occurred, since I hadn't completed any voucher writ for a while.
