As the title mentions, the treasure Sr.Tomb Diver of Reno requires more than 3 secrets to activate.
You didn’t count secrets put into field by other passive treasure, did you…?
Well all of the secrets I put were from my hand, not passive nor from minion’s battecries.
Replays could be useful for investigation.
Thanks for your reply. I played again, everything is fine now, maybe it was just a short hiccup from server side.
