Me too. I have attacked NPC lv 5. And cant not catch hero. It waste of my time when i spend 6 days for trainning my troops and resource.

Now in my hero quests are only catch
quest #name# quest
quest #name# quest

but in My Item " tab quest " I have 3 icon of 3 heroes that i have spent 30 cents.

I attack NPC lv 5 and win it said you win but "conqueres unsucessfully" and
no information about hero i need to catch in that NPC city.

any suggestions? bug or what?
