I am sure it s not a common bug, or however it is addressed, so here we go i ll try to explain it since it might not be a bug before introduction of tavern passes.
When you reach level 100 on it in NON-paid track, you can choose one skin out of the some options for different classes.
Now i reached it last expansion and i havent manually clicked reward AND have chosen the skin, among the all other plenty rewards i have had there hanging unclaimed.
Now new expansion “Into The Emerald Dream” launched, there is a new tavern pass and system in HS works that if you have any rewards unclaimed when the new tavern pass hits and old one goes away and it can not be CLICKED on level 100 anymore since there is new one here, so lets continue , it auto claimes all of those unclaimed rewards, BUT there is a problem with claiming lvl 100 reward, because whats different there, as i mentioned already, it needs to be manually clicked on the skin, so i dont get the option to choose what skin i should get, i just get NOTIFICATION upon logging fro the whole expansion there are unclaimed rewards from old one.
So i would like to suggest it to be changed, so i can claim the skin, OR maybe, it auto claims any of the option that i can choose from, randomly or something.
I dont like that i get pop up that i have unclaimed rewards, but system cant pick it up and it doesnt let me choose.
TLDR: I am not given an option to select ONE of the skins on old tavern pass lvl 100 reward and i cant CLICK to choose one because it is OLD tavern pass and i cant enter pass, maybe it needs to randomly choose one of those options or something.
This is indeed a bug:
