Did you change anything in last update?
Since last update blocks with more than 1 Round are not working properly. I know that blocks are not supported in theory by the game but in that case what is the use of veteran general characteristic (attacks are 1/2 time of normal generals)....
I can say that I'm a block specialist, i have made my own guide, and i have been doing blocks for months... now without any notice you changed something because in last adventures that i tried triple-blocks I lost a lot of troops.
Can you confirm this?... if it is, then i will stop playing adventures since it was the only interesting thing.
Best regards
