@GaiaByte I double checked. There was no x10 disaster, no x3 multiplier, no UM. I can't be sure if there was any change in followers now. But I can be 100% certain that the chest count below the hero chest didn't add one. It was still 0 after the key was gone. I think this is a strong indication that the key didn't take effect.
I lost a chest key just now. Right after I got the key from the daily quest, I went to the chest page and clicked "open". It lagged a while and nothing happened. I clicked "open" again, and a message popped out saying "can't use". I then refreshed the whole game and went back to the chest page, and the key was gone. I didn't receive any reward, and the hero chest count didn't add one. It's obvious that the key was lost, maybe due to connection problem. @GaiaByte
The "save level" talent is so useless. It doesn't make the upgrading faster like the "start level" talent. It gives absolutely zero benefit on rebirth. I want to turn it off but there's no way to do that except a hard reset.
AI has serious flaws.
In the arena, when an AI is cornered, it just stop doing anything, forcing the player to resign, which is ridiculous because it is the AI who's about to lose.
In the caverns, a support character somehow thinks he is a tank and goes straight into herds of monsters while he should stay behind summoning and healing. This happens when the AI setting is support>interference>DPS ranged>DPS close>tank.
@Gaiabyte Now my result of tournament 5/7/2017 shows "Tournament hadn't finished" instead of my rank and reward. What does that mean? I still think there was a glitch when I clicked the join button and my 100 UM was lost in vain.
