Glitched Mobs in Elite Shuyal Shadow Plains !

So we were doing Elite Shuyal Shadow Plains for AP's when we came to boss we had to kill mobs around it so we can attack heart so while we were killing mobs one of my friends used stampys AA and he stunned them or something else like somone elses skill or pet stunned them acctually it doesnt matter,but they stood stunned for 10minutes until we restarted them...Its really wierd bug i think stampy caused it but it may be caused bysomething else, still its wierd.Dont watch time we stood afk for long time xD.What do you think about this?
