Jamie/Enzo Bug ?

hello,

is the weak point attack activation supposed to be triggered by Jamie when the troops are healed?

However I have a report on which Jamie triggers the weak point attack on the lancers BUT also on the cavalry that is placed on the back line while no rider is injured.

If this is a bug, players exploit this bug by putting 1000cav in 2nd line and Enzo. Thus the damage caused by weak point attacks increases much faster and benefits the INF or spears in the 1st line :(
