I really enjoyed this game after my first day playing it. However I’ve encountered my first bug.
I bought my first Knight in the Hero shop with a few hundreds crystals. While the crystals are gone, the Knight is not in my list of heroes (even after restarting and waiting a full night).
I was in the metro when I did the purchase, maybe the connection broke and only half of the transaction was successful.
I don’t remember its name, I just remember it was a cheap knight, as I’ve played only yesterday and I have not spent any real money yet.
As I played only one day, I guess it’s not a big loss. I’m more interested in making the game better, so you might want to report this bug to the dev team to try to implement a real transaction protocol in your backend (Lock, Transaction, Submit or Cancel). I tried to click send log to the dev team, not sure if it’s useful.
