First off I love this game! Even tough it's bugged like hell.
Yesterday I encountered a few annoying bugs wich I want to mention.
1. I summoned a Ice Lord, did Ice Blast on a enemy and poof just like that he disappeared!
Now I can't use the only magic attack of my Ice Lord! What good will this creature do to me if I can't use the Ice attack of a Ice monster???
The only way to solve this issue is to press the autoresolve button! 
2. This bug is even worse! I got attacked in my city, I have 5 summons and 3 armies of 3. I defend the city without any casualties, but after the battle all my summons and soldiers are gone!!! It was the first and only time I got attacked in my own city, so I have to test if this happens every time when I have to defend my city. Maybe it's important to point out that the city I defended was occupied by me 2 turns earlier. This also wiped out that faction.
3. Another disappearance bug. I noticed that some of my summons just vanish even tough they didn't die in battle...
I can resummon them, but to summon a fire monster (16 mana) takes me up 16 turns before I can do this. And I don't have and can't buy mana refill potions yet. I found 2 of them along the way but that's it. There should be an option where your mana get's filled faster when you are in your city and have full health...
That's it for now, I report back if I encounter more bugs which aren't mentioned yet! 
Peace!
Edit: My Ënd Turn" button broke! I keep pressing it but somehow it decided not to work anymore! I'm at turn 215, now I have to start a new game... again!!!
