Option to move from top of deck to the stack performs a full cascade the first time you try to do it in the session. If you press the cascade varient first it will no longer happen and will not be reproducable until you completely restart cockatrice
Once a proper cascade is performed once it will no longer happen even if you disconnect from a match and connect to a brand new one, so there is an improperly initialised variable or something that preserves between matches.
