Doing about 3+ adventures a day and this has happened a few times.
Normal general blocking a camp: No attack animation, camp still intercepts other incoming generals. After certain time the camp fight will commence still.
So if doing a block with 170 elites, the general will attack yet my other generals still get intercepted losing all my elites as I now have to retreat the main attacks.
This has led to the loss of about 600 or so elites this week.
