Look at the photo , i have 2 serpent queen. 1 lvl 62 and one lvl 60. When i go to the arena , it only shows the lvl 62 serpent queen only. Second bug , i have 830 shards , but when i click elites or legend slime , the shards number is in red and i cant buy it. Im wondering is this also a cause to my shards farming as my shards is totally zero these few days
I think your first bug is not a bug, I think it doesnt show duplicates in the arena, only the highest level hero.
This happened to me when I had 2 druids.
You have 2 werewolf, try to see if you can use both or only 1.
The other bug is often happening to me, especially when I reach a certain amount of shards and wanna buy a slime, the number will be in red but you can still buy it.
So it rly doesnt matter.
Actually when you just reached the right amount of shards, even the number under a hero will be in red, but if you try to buy it, it will work.
