Did a defense of crete run "hard difficulty" but i had "no quest"

After tons of tries not to get horde archers at the start, me and my friend managed to do defense of crete on hard difficulty for the first time (because our levels are 20 and 23). After the run i was so excited to see what's inside the chests but unlike my friend i was shocked that there was no quest to deliver and i spent like 2 hours for nothing, to be honest i got some crappy xp.

So, was that a bug or something? I know, this game is new and all and it needs time to improve.. but an error like that is really unforgivable..

Is there a way to contact someone and ask for help? I dont think so... because this is a "free game" ( no, they are not making tons of money out of it)... so they can't afford hiring game masters or anything..

Seriously, this game is cute and i like it, but the way you are laughing at us is making me start to hate it..
