I have run Black Knights four times in the last week and every time, during an attack, there has been a connection error. One of those times I lost Cannons and Elites because I was supposed to retreat after hitting an intercepted camp, but I wasn't there to do it.

The other times active attacks had completed as expected when I return, which was a relief.

The error always happens when two or more attacks are active.

I haven't had this issue with Bandits Nest or Tomb Raiders. It just happens on Black Knights.

Thanks for your time.
