It has happened a few times, and I am kinda getting annoyed about it. So when i try to do a clan battle and I am loading up the battle, I sometimes disconnect from the server (lose connection or servers are down) Today I went and loaded but it said I disconnected to the server, I am not quite sure if it was maintenance or just bad connection. So I waited about an hour to do the clan boss. When I am about to click Battle it wont let me cause I apparently wasted the key. poof gone it doesn't even show I attacked the boss. Its kinda annoying because I have to wait more hours. I think this also happens when you summon champs from shards, it has only happened once to me and it was a mystery shard so its not important. I do not know if anyone else has this problem or if ti can even be fixed but it feels like it takes away the clan key right before the battle starts which may be the problem but it may just because I lose connection to the game right before it starts and it eats the key. I do not mind this happening to me since its only been maybe 4-5 times. Just wondering if its a bug.
