The game i just had some units bugged, when i had them in my inventory they ware unsellable and had a red hp bar. when placed on the board they ware neutral, so they attacked friendly and enemy units. so i was stuck with them all game.
I had the same problem. I even got a screenshot, but don't know how to upload a picture in this forum.
My problem occurred using the glitch after the carousel having one more champ on the field and a full bench. After I won the next fight without loosing a champ I sold one unit on a bench, but couldn't refill it with another purchase.
In the beginning of the next round one of my champs was ported back on my bench with a red hp bar. That champ was neutral and I couldn't sell ist.
But I could place it onto the field and even exceed my champion limit, (6/5). So in the next fight I had a neutral champ and five of my units on the field and space in my bench.
In the end I bought two more units and lvl up the neutral champ and I could use the lvl2 champ normally.
